The document discusses bipartite matching and describes how to find the maximum matching between two disjoint sets using the augmenting path algorithm. It explains that the algorithm works by searching for augmenting paths between unmatched vertices, reversing any that are found to increase the size of the matching, and repeating until no more augmenting paths exist. The time complexity of this algorithm is O(V×E) where V is the number of vertices and E is the number of edges.
In graph theory, a matching is a subset of a graph's edges such hat no two edges meet the same vertex. A matching is maximum if no other matching contains more edges. A trivial solution (exhaustive search) to the problem of finding a maximum matching has exponential complexity. We illustrate polynomial time solutions to the problem that were published between 1965 and 1991.
General Linear Model is an ANOVA procedure in which the calculations are performed using the least square regression approach to describe the statistical relationship between one or more prediction in continuous response variable. Predictors can be factors and covariates.

Knapsack problem ==>>
Given some items, pack the knapsack to get
the maximum total value. Each item has some
weight and some value. Total weight that we can
carry is no more than some fixed number W.
So we must consider weights of items as well as
their values.
Use C++ to Manipulate mozSettings in GeckoChih-Hsuan Kuo
If you want to manipulate mozSettings with JavaScript, you can reference to Settings API on MDN (https://developer.mozilla.org/en-US/docs/Web/API/Settings_API).
But if you want to manipulate it with C++, we can only reference to the codebase of Gecko. Now, let me show you some example.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

• The length of an augmenting path
always is odd.
• Reversing an augmenting path will
increase the cardinality.
• If there is no augmenting path, the
cardinality is maximum.

1. Try to build augmenting paths from all
vertices in one side.
2. Travel on graph.
3. If an augmenting path exists, reverse

this vertex.

augmenting path exists.
