`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).

`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"])
```
