The file "simulations.cpp" contains the code used for the experimental evaluations appearing in the paper "Efficient Online Learning of Optimal Rankings: Dimensionality Reduction via Gradient Descent". The function "Generate_Request" generates the two different types of requests described in Section 5 (see the comments inside the function to switch between the two). The file "make_plots.py" produces the plots appearing in Section 5. The value of the argument "Times" in function "Generate_Request" must agree with the value of the variable "Copies" in "make_plots.py".
