Scope and architecture
Global Optimization Toolbox offers selected MATLAB-based global and nonsmooth search methods. CPLEX Optimization Studio targets supported mathematical programming and constraint problems. The objective, constraints and variable types should determine which methods are appropriate.
Solver fit depends on objective and constraint structure, variable types and mathematical assumptions. A global search method does not guarantee the globally optimal answer for every problem. Toolbox and solver licences, supported interfaces and deployment rights must be checked separately.
