This paper addresses the challenging task of computing multiple roots of a system of nonlinear equations. A repulsion algorithm that invokes the Nelder-Mead (N-M) local search method and uses a penalty-type merit function based on the error function, known as 'erf', is presented. In the N-M algorithm context, different strategies are proposed to enhance the quality of the solutions and improve ...
In this paper, we discuss the training of a tetris playing AI using a combination of Nelder-Mead optimization and genetic algorithms. The core AI consisted of a variable depth look-ahead player optimizing a set of 16 features, built on the core Java code provided by the TA. A set of random scores were optimized using MATLAB’s implementation of Nelder-Mead, fed through a genetic algorithm, then ...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
State transition algorithm (STA) is a metaheuristic method for global optimization. However, due to the insufficient utilization of historical information, it still suffers from slow convergence speed and low solution accuracy on specific problems in later stages. This paper proposes hybrid STA based Nelder–Mead (NM) simplex search quadratic interpolation (QI). In exploration stage, NM utilizes...
In recent years, there has been a great deal of interest in metaheuristics in the optimization community. Tabu Search (TS) represents a popular class of metaheuristics. However, compared with other metaheuristics like genetic algorithm and simulated annealing, contributions of TS that deals with continuous problems are still very limited. In this paper, we introduce a continuous TS called Direc...
An open-source data-analysis framework 2DMAT has been developed for experimental measurements of two-dimensional material structures. offers five analysis methods: (i) Nelder-Mead optimization, (ii) grid search, (iii) Bayesian (iv) replica exchange Monte Carlo method, and (v) population-annealing method. Methods through are implemented by parallel computation,which is efficient not only persona...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...

The focus of this research was to formulate optimization model 16-bar trussesalong with stress, stability and deflection constraints. derivative free methods were used for theoptimization engineering design problems. These basically designed forunconstrained In formulated truss problems the constraints werehandled by using exterior penalty functions. results obtainedby MATLAB which demonstrated...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
