چکیده

This paper introduces a new variant of the Backtracking Search Optimization Algorithm (BSA) in order to improve the quality of the solutions found by the algorithm. The proposed algorithm is called Idol-Guided Backtracking Search Optimization Algorithm (IG-BSA): it uses the historical population defined in BSA to build and update a set of idols taken from several previous generations, and the current population evolves under the influence of these idols. Moreover, in contrast with BSA, we add a diversification strategy in case of stagnation. An experimental study with 19 widely used benchmark problems is presented. Numerical results and statistical tests show that IG-BSA outperforms BSA, CMAES, and SPSO2011.

One-Dimensional Modeling of Helicopter-Borne Electromagnetic Data Using Marquardt-Levenberg Including Backtracking-Armijo Line Search Strategy

In the last decades, helicopter-borne electromagnetic (HEM) method became a focus of interest in the fields of mineral exploration, geological mapping, groundwater resource investigation and environmental monitoring. As a standard approach, researchers use 1-D inversion of the acquired HEM data to recover the conductivity/resistivity-depth models. Since the relation between HEM data and model ...

A GUIDED TABU SEARCH FOR PROFILE OPTIMIZATION OF FINITE ELEMENT MODELS

In this paper a Guided Tabu Search (GTS) is utilized for optimal nodal ordering of finite element models (FEMs) leading to small profile for the stiffness matrices of the models. The search strategy is accelerated and a graph-theoretical approach is used as guidance. The method is evaluated by minimization of graph matrices pattern equivalent to stiffness matrices of finite element models. Comp...

A Memetic Backtracking Search Optimization Algorithm for Economic Dispatch Problem

Economic load dispatch (ELD) is a non-linear optimization problem for determining the power shared among the generating units to satisfy the generation limit constraints of each unit and minimizing the cost of power production. In this paper, we present a new hybrid algorithm by combing the standard backtracking search optimization algorithm (BSA) and the random wake with direction exploitation...

An Empirical Study of Multi-Point Constructive Search for Constraint Satisfaction

Multi-Point Constructive Search (MPCS) is a constructive search technique which borrows the idea from local search of being guided by multiple viewpoints. MPCS consists of a series of resource-limited backtracking searches: each starting from an empty solution or guided by one of a set of high quality, “elite” solutions encountered earlier in the search. This paper focuses on MPCS as applied to...
