Solver
OptQuest Solver Engine Version
Introduction
The OptQuest Solver Engine employs metaheuristics such as tabu search and scatter search to solve nonsmooth optimisation problems of up to 5,000 variables and 1,000 constraints. It is a new field-installable engine that plugs into the Premium Solver Platform and takes advantage of its Polymorphic Spreadsheet Interpreter. The engine handles models with any Excel formulas and functions, yet finds remarkably good solutions with unprecedented speed. Furthermore, it supports integer variables and 'alldifferent' constraints.
