Generating set search

WebThe generating_set_search often gives best results (its MedianLogTimesWorseFitness is 0.6, which means its median fitness value is 10^0.6=3.98 times worse than the best found) and is faster (ranked first on run time often) but it is not as robust as the DE optimizers and thus is ranked lower on mean rank (per problem). WebMay 1, 2024 · In the single-objective setting, simplex derivatives have been used to accelerate (generalized) pattern search (Custódio and Vicente 2007) and generating …

Global Optimization Toolbox functions include … We call this method (simplex) gradient-informed generating set search, or GIGS for short. While the use of simplex gradients for directly determining the search pattern is novel to the best of our knowledge, previous works have explored applications of the concept in the DFO context.
