The document presents a modification to the Jaya optimization algorithm. The standard Jaya algorithm seeks guidance from only the best and worst solutions in each iteration. The modification proposes that Jaya should also seek guidance from the top and bottom 10% of solutions, in addition to the best and worst. This allows information to flow more continuously from the extremities.
The proposed algorithm is tested on the sphere function optimization problem. Initial candidate solutions are generated and ranked. The top and bottom 10% solutions near the best and worst are identified. Each candidate is then modified based on these neighboring solutions, moving toward the top 10% and away from the bottom 10%. Finally, candidates are refined using the standard Jaya equations seeking guidance from the

Branch and Bound technique to solve Integer Linear ProgrammingKaivalya Shah
Introduction to a technique for solving Integer Linear Programming problems, made as a part of Design and Analysis of Algorithms course in 5th semester.
The document describes the linear programming model and the simplex method for solving linear programming problems.
The linear programming model involves maximizing a linear objective function subject to linear inequality constraints involving decision variables. The simplex method is then used to solve linear programming problems by iteratively arriving at optimal feasible solutions.
The method involves setting up an initial tableau with slack variables, then selecting entering and leaving variables at each iteration to improve the objective function value, arriving at a final optimal solution where all coefficients in the objective function are positive. An example problem demonstrates applying the simplex method graphically and through tableau iterations to find the optimal product mix for a company.

Standard form additionally requires right sides of constraints to be non-negative and constraints to be expressed as equations using slack or surplus variables.
2. The key difference between canonical and standard form is that standard form represents constraints as equations using slack/surplus variables while canonical form uses inequalities. Standard form simplifies the canonical form for applying the simplex method of solution.

Linear algebra application in linear programming Lahiru Dilshan
Linear programming is used to maximize or minimize quantities subject to constraints. It can be applied to problems with any number of variables and constraints, as long as the relationships are linear. Key aspects include defining an objective function to optimize, determining the feasible region where all constraints are satisfied, and finding extreme points where the objective function may be maximized or minimized.

MOCANAR: A MULTI-OBJECTIVE CUCKOO SEARCH ALGORITHM FOR NUMERIC ASSOCIATION RU...cscpconf
Extracting association rules from numeric features involves searching a very large search space. To
deal with this problem, in this paper a meta-heuristic algorithm is used that we have called
MOCANAR. The MOCANAR is a Pareto based multi-objective cuckoo search algorithm which
extracts high quality association rules from numeric datasets. The support, confidence,
interestingness and comprehensibility are the objectives that have been considered in the
MOCANAR. The MOCANAR extracts rules incrementally, in which, in each run of the algorithm, a
small number of high quality rules are made. In this paper, a comprehensive taxonomy of metaheuristic
algorithm have been presented. Using this taxonomy, we have decided to use a Cuckoo
Search algorithm because this algorithm is one of the most matured algorithms and also, it is simple
to use and easy to comprehend. In addition, until now, to our knowledge this method has not been
used as a multi-objective algorithm and has not been used in the association rule mining area. To
demonstrate the merit and associated benefits of the proposed methodology, the methodology has
been applied to a number of datasets and high quality results in terms of the objectives were

Cuckoo Search: Recent Advances and ApplicationsXin-She Yang
This document summarizes recent advances and applications of the cuckoo search algorithm, a nature-inspired metaheuristic optimization algorithm developed in 2009. Cuckoo search mimics the brood parasitism breeding behavior of some cuckoo species. It uses a combination of local and global search achieved through random walks and Levy flights to efficiently explore the search space. Studies show cuckoo search often finds optimal solutions faster than genetic algorithms and particle swarm optimization. The algorithm has been applied to diverse optimization problems and continues to be improved and extended to multi-objective optimization.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence
