GLOBAL Reproducibility of Results

This section gives instructions on reproducing the numerical results in the paper

Pinter, J (2003), GAMS/LGO Nonlinear Solver Suite: Key Features, Usage, and Numerical Performance, Submitted.

Version/Platform:

GAMS 21.2 (Linux).

Preliminaries

Download the GLOBALLib library of models: globallib.zip
Download the GAMS scripts to run the experiments
- go_test_fig1.gms
- go_test_fig2.gms
Download the termination routines described in the section on Program Termination These tools are necessary to independently ensure that solvers are allocated a set resource solver time.
- The GAMS routine schulz.gms
- PSList (Download and place into your GAMS system directory)
- PSKill (Download and place into your GAMS system directory)
The tools PSKill and PSList are free from but proprietary from Sysinternals.

Reproduce Results in Figure 1

Run the schulz.gms termination routine. From the command line
```
    >> gams schulz.gms --resseq=65:70:75
      
```
On Windows: Add the flag --watch=gms*
Run the GAMS script gotest_fig1.gms. From the command line
```
   >> gams gotests_fig1.gms 
   
```

This will create the following trace files which can be submitted to the PAVER Server for analysis. When submitting make sure to rename the solver names as follows (otherwise, the PAVER submission will fail)

        TRACE FILE           RENAME SOLVER TO

        lgo-1_fig1.pvr            LGO-1 
        lgo-2_fig1.pvr            LGO-2 
        lgo-3_fig1.pvr            LGO-3 
        lgo-4_fig1.pvr            LGO-0

Reproduce Results in Figure 2

Run the schulz.gms termination routine. From the command line
```
    >> gams schulz.gms --resseq=65:70:75
      
```
On Windows: Add the flag --watch=gms*
Run the GAMS script gotest_fig2.gms. From the command line
```
   >> gams gotests_fig2.gms 
   
```
