Path-relinking is major enhancement to heuristic search methods for solving combinatorial optimization problems, leading to significant improvements in both solution quality and running times. We review its fundamentals and implementation strategies, as well as advanced hybridizations with more elaborate metaheuristic schemes such as genetic algorithms and scatter search. Numerical examples are...

Solving optimization problems is an ever-growing subject with enormous number of algorithms. Examples such algorithms are Scatter Search (SS) and genetic Modifying improving can be done by adding diversity guidance to them. Chaotic maps quite sensitive the initial point, which means even a very slight change in value point would result dramatic sequence produced chaotic map Arnold's Cat Map. Ma...

This tutorial will focus on several new real-world applications that have been developed using an integrated set of methods, including Tabu Search, Scatter Search, Mixed Integer Programming, and Neural Networks, combined with simulation. Applications include project portfolio optimization and customer relationship management.

In this work we consider the application of two metaheuristics, namely evolution strategies and scatter search, to the problem of fitting rectangular signals to time-data series. The application background is to search for exoplanet-transit signals in stellar photometric observation data.

PURPOSE To assess the crystalline lens opacity level by measuring ocular light scattering with a double-pass system. DESIGN Prospective, single-center, cross-sectional study. METHODS Two hundred fifty-three eyes of 135 patients referred for cataract evaluation were enrolled. Patients with corneal or retinal anomalies potentially impairing ocular transparency were excluded. Lens opacificatio...

PURPOSE To evaluate whether correlations exist between objective and subjective measures of vision quality as a consequence of cataract and whether this may qualify the Objective Scatter Index as a supplementary means of cataract assessment. METHODS A prospective multicenter, cross-sectional study was conducted in 10 centers across France in patients undergoing cataract extraction surgery (le...
