%This code is the stating point for running the REGO and XREGO
%experiments. 

%framework - choose the framework you want to test, i.e., 'no embedding_vs_REGO', 'REGO', 'AREGO'
%name_of_solver - choose the solver you want to test with, e.g., DIRECT, BARON, KNITRO
%list_of_functions - a text file that contains a list of functions that the user would like to solve,
%list_of_functions must be a column of strings, e.g., ["Beale_10"; "Hartmann3_100"; ...]
