# FuzzOpt - Fuzzing LP/ILP Optimization Solvers
## Getting Started
Fuzzing usually takes prolonged time and optimization solvers are demanding in resources.
Therefore, it is desirable to deploy the fuzzing procedure on Euler.
First, we need to install the two optimizers of interest, Cplex and Gurobi.
To install Cplex, go to the download page of Cplex and choose the Linux version and download it to your local laptop.
Then you can copy the `.bin` file to the Euler whichever way you like (e.g., `scp` or FileZilla).
On Euler, execute the `.bin` file by
```bash
chmod a+x <filename>
./<filename>
```
Follow the instructions shown on the screen and when it asks where to install the binary, instead of using its default option, make the installation into your local home directory.
For example, you can specify the installation path as `/cluster/home/<user name>/ibm/ILOG/CPLEX_Studio_Community221/`.
You do not have permission to install in `\opt`.
Once the installation is done, install the Cplex python API by
```bash
python /cluster/home/<user name>/ibm/ILOG/CPLEX_Studio_Community221/python/setup.py install
```
Try if it works by typing `python -c "import cplex"`. If it prints nothing, it works.
Moving on the Gurobi, Euler has Gurobi installed as modules so we only need to load them and install the python API.
For loading,
```bash
env2lmod # switch to the new software stack if you haven't
module load gurobi/9.5.1
```
To install the python API, do
```bash
python -m pip install gurobipy
```
Check if it works -- `python -c "import gurobipy"`.
Now you have all dependencies ready.
Note: you will need to load the Gurobi module every time you log into Euler. To avoid this, add the following line to `.bashrc`, which will load the module automatically.
```bash
module load gurobi/9.5.1
```
