 SOF was designed to execute simulation optimization and parameter space exploration process on Apache Hadoop. In order to execute a simulation optimization process the user must provide a well formatted input:
 * the simulation executable, MASON/NetLogo model or an executable file;
 * the selection and evaluation functions written in any languages supported by the cluster machine (in this case the user must also define the interpreter program path for languages like Python, Groovy etc.);
