ROI.models.globalOptTests

globalOptTests

library(ROI)
library(ROI.models.globalOptTests)

globalOptTests is a R package which contains several non-linear programming problems with box constraints. More information about globalOptTests can be found in Mullen (2014).

Using ROI.models.globalOptTests

globopt()

lists all the names of the globalOptTests instances.

globopt(x = "all")

gives all the globalOptTests instances converted into a ROI optimization problem.

globopt(x = "metainfo")

gives the available meta information.

globopt(x = "Rastrigin")

returns the Rastrigin optimization problem as an ROI optimization problem.

z <- ROI_solve( globopt(x = "Rastrigin"), start =  double(10))
abs(solution(z, "objval") - globopt("metainfo")["Rastrigin", "optimum"])
