Evolutionary algorithms are optimization techniques inspired by biological evolution. They work by generating random solutions and using mechanisms like selection, crossover and mutation to iteratively improve the population's fitness. Genetic algorithms are a popular type of evolutionary algorithm that mimics Darwinian evolution by maintaining a population of candidate solutions and using techniques like crossover and mutation to produce new solutions from existing ones. An example demonstrates how a genetic algorithm can be applied to optimize a function by evolving a population of potential solutions over generations.
Genetic algorithms are a class of evolutionary algorithms inspired by Darwinian evolution. They were developed in the 1970s and are typically applied to discrete optimization problems. The simple genetic algorithm uses binary representations, one-point or uniform crossover, bit-flip mutation, and fitness-proportionate selection. It emphasizes combining information from parents through crossover. While effective, it has some limitations like restrictive representations and sensitivity to converging populations. Many variants of genetic algorithms have been developed that use different representations, operators, and mechanisms to address these issues.
Performance of genetic algorithm is flexible enough to make it applicable to a wide range of problems, such as the problem of placing N queens on N by N chessboard in order that no two queens can attack each other which is known as ‘n-Queens problem.
Lack of information about details of the problem made genetic algorithm confused in searching state space of the problem

It describes genetic algorithms as probabilistic optimization algorithms inspired by biological evolution, using concepts like natural selection and genetic inheritance.

Volume of data available in the digital world is increasing every day at a greater speed. Due to enhancement of various technologies and new algorithms, extraction of essential data from huge volume of data is not a tough task nowadays but our goal is the extraction of patterns and knowledge from large amounts of data. Different sources are available for collecting the reviews about a product. To enhance the quality of the products and services these reviews provides different features of the products. Models can use one or more classifiers in trying to determine the probability of a set of data belonging to another set, say spam or 'ham'. Depending on definitional boundaries, modeling is synonymous with, the field of machine learning, as it is more commonly referred to in academic or research and development contexts. In this paper we identified and discussed about three algorithms which are efficient in identifying essential patterns in the available huge volume of data.

The algorithm iterates until a termination condition is met, such as a solution being found or a maximum number of generations being produced. Genetic algorithms are useful for optimization and search problems as they can handle large, complex search spaces. However, they require properly defining the fitness function and tuning various parameters like population size, mutation rate and crossover rate.

They work by generating an initial random population of solutions and then applying genetic operations like selection, crossover and mutation to produce new solutions over multiple generations. The fittest solutions survive and weaker ones die out, causing the overall population to become better adapted to the problem being solved. Genetic algorithms are well-suited for searching large, complex datasets and problems with multimodal or n-dimensional search spaces.

This document summarizes a presentation on active noise control fundamentals and recent advances. It discusses the history of active noise control from the 1930s to present day, covering milestones such as the first patent in 1936, emerging analog devices in the 1950s, the introduction of adaptive noise cancellation using digital signal processing in the 1970s, and the development of digital active noise control systems and applications from the 1980s onward. It also outlines topics to be covered on active noise control fundamentals and recent advances in two parts of the presentation.
This document presents a remote FxLMS algorithm for active noise control in remote locations. It introduces the concept of active noise control to cancel noise using secondary sources. A novel model is proposed to analyze active noise control systems in the acoustic domain. Based on this model, a methodology is developed for active noise control at remote locations using a remote FxLMS adaptive algorithm. Results show the remote algorithm can effectively control noise at a distant point. Future work aims to target 3D zones of quiet in remote locations.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Geometry (as a knowledge), he tried to solve the first
optimization problems. Examples are:
1. What is the shortest path between two points?
2. How to break a stick to make a rectangle with maximum
area?

11. There are many different EA algorithms, the basic
of which can be explained through Genetic
Algorithms.
They are all random-based solution space
searching meta-heuristic algorithms.

12. Mendel (1822-1884) – Philosopher and scientist
cultivated and tested about 29,000 plants between 1856 and
1863 to verify his laws of heritance. Mendel's work was rejected
at first, and was not widely accepted until after he died.
Darwin (1809-1882) – Scientist
developed his evolution theory, stating that evolution is the
change in the inherited characteristics of biological populations
over successive generations.
Evolutionary Algorithms
Evolutionary algorithms are based on the basic principles of Mendel’s
foundation of genetics and Darwin’s theory of evolution .

electrical engineering at the University of Michigan
The main idea of genetic algorithm is that every individual of a
species can be characterized by its abilities that help it to cope
with its environment in terms of survival and reproduction.

14. A genetic algorithm is a search heuristic algorithm that mimics
the process of natural evolution. It has 5 phases:
Genetic Algorithm
1. Population
Generation
2. Fitness
Evaluation
4. Crossover
5. Mutation 3. Selection
By Iman Ardekani
15. Phase 1: Population Generation
Individuals
1. Individuals = a sample from the solution space (each individual
is a solution)
2. Generation = a group of individuals
Genetic Algorithm
individual 1 individual 2 …. individual N
Population | Popsize = N

16. Phase 1: Population Generation
Population Generation Rules
1. The first generation is produced randomly.
2. Next generations are produced through breeding.

Chromosomes and Fitness
Each individual has two properties:
a) Its location (chromosome composed of genes)
b) Its quality (fitness value)
Genetic Algorithm

18. Phase 2: Fitness Evaluation
Fitness value of an individual is usually the value of the cost-
function (to be optimized) with respect to the locations (genes)
of the individual.

19. Phase 3: Selection
After evaluating the fitness of all individuals, we use a selection
process to generate a mating pool.
Each individual may be selected several times.
Even low quality individuals have chance to be selected.
Individuals in the mating pool are called parents.
Genetic Algorithm
By Iman Ardekani
20. Phase 3: Selection
Selection Rule:
1. Higher quality = more chance of being selected into the mating pool
Example:
Genetic Algorithm
Individual Fitness Relative
1 90 45%
2 60 30%
3 20 10%
4 30 15%

21. Phase 4: Crossover
Two parents might be selected randomly from the mating pool
to generate two offspring.

23. Phase 5: Mutation
There is a very low chance for (small) changes in the genes of
the offspring; however, it should be considered.
Mutation = Small changes in the genes of an offspring

1. We can divide the solution space into 212 sections.
2. In this case, each solution value can be represented by a 12-bit
binary number.
3. This 12-bit representation can be considered as Chromosome
4. Each bit can be considered as a gene.

30. Steps to follow:
1. 10 random value for x (individuals) leads to 10 chromosomes.
2. The fitness value of each individual can be found as y=f(x).
3. The relative fitness can be then obtained accordingly.
4. Based on the relative fitness values, a selection wheel can be
created.
5. A mating pool can be created by using the selection wheel.
6. Two individual can be selected from the mating pool as
parents.

31. Steps to follow:
7. A random number is generated. If the random number is
higher than a certain level (crossover probability), the
crossover will happen.
8. Otherwise, two other parents will be selected and step 7 will
be repeated.

34. Steps to follow:
10. For each gene of each child, a random number will be
generated. If the number is higher than a certain value
(mutation probability – very low) then the value of the gene
will be changed. Otherwise, the gene remains untouched.
Example
1 0 1 0 0 1 0 0 1 0 0 1Child 1
1 0 1 0 0 0 0 0 1 0 0 1Child 1

will be add to the next generation.
12. Step 7 will be repeated until the size of the new generation
becomes equal to the Popsize.
13. Step 2 will be repeated for the new generation.

I think there are some drawbacks for evolutionay algorithm. For example, they can find an optimum solution but the process of obtaining this solution is not optimum.
Many people think that evolutionary algorithms work in the way that the evolution works in the nature. So study of these algorithms might be interesting.
Personally, I am not very keen to these algorithms but understanding them could be useful.
For example, data can be daily temperature of a region. The numbers representing daily temperature should be analyzed in order to create graphs for studying the climate of a region. The graphs or information can represent seasonal temperature or annual temperature. After collecting data and producing information for so many years we can analyze the information and create knowledge for forecasting the climate of that particular area.
Forecasting is a kind of optimization problem. Because you are going to use your knowledge for finding the best possible answer. Back to our previous example, after creating the knowledge of climate in a particular region we can move towards forecasting the climate in that area.
These are deterministic optimization problems because the problem is defined a deterministic problem with certain values for parameters. However, an optimization problem can be defined in a problem domain with high level of uncertainty. This means that some parameters can have some stochastic characteristics.
Lets have a look at the optimization problem in view point of classic mathematics. But the question here is “can we deal with all of the optimization problems using this approach?”… and unfortunately, the answer is a No.
