The computer on which this example is published has four cores, so parpool starts four MATLAB® workers. To use the parfor feature, we use the parpool function to set up the parallel environment. Similarly, ga, gamultiobj, and patternsearch solvers in Global Optimization Toolbox evaluate functions in parallel. The finite differencing used by the functions in Optimization Toolbox to approximate derivatives is done in parallel using the parfor feature if Parallel Computing Toolbox™ is available and there is a parallel pool of workers.

Serial GA optimization takes 80.2351 seconds. Optimization terminated: maximum number of generations exceeded. Generation Func-count f(x) f(x) Generations Note that running ga requires Global Optimization Toolbox. We are interested in measuring the time taken by ga so that we can compare it to the parallel ga evaluation. In addition, we limit the maximum number of generations to 15 for ga so that ga can terminate in a reasonable amount of time. Since ga usually takes many more function evaluations than fmincon, we remove the expensive constraint from this problem and perform unconstrained optimization instead. Serial FMINCON optimization takes 17.0722 seconds. Optimization completed because the objective function is non-decreasing inįeasible directions, to within the value of the optimality tolerance,Īnd constraints are satisfied to within the value of the constraint tolerance.
