optimize {nlopt}

Optimizes the problem

Description

Function that calls the corresponding solver with custom options to solve the problem given by the .nl file

Usage

optimize(solver, file, options)

Arguments

solver

name of the solver (it has to be in the PATH)

file

.nl file with the optimization problem. If the name of the file starts with MINLPLib:: then the problem will be downloaded from MINLPLib library

options

list with the options for the solver

Value

list with a string of the output given by the solver (output), the optimal value of the problem (objective), the status returned by the solver (status), the optimal primal solution (primal_solution), and the optimal dual solution (dual_solution)

Examples

optimize(solver = "ipopt", file = "MINLPLib::alkyl", options=list(max_cpu_time=300, outlev=3))
