Calculation of string tension

I have installed the SIMULATeQCD code in my userspace located in /root/project1/ of container named virat.
I have build the all executables by command 'make -j 19', it worked in almost 80 minutes.

The objective and calculation of the project is explained in the link.

Wilson Loop code

Bresenham algorithm we can't choose all paths, as there are 12884901758 paths for \(32\times32\times32\times8\) which can be calculated from bresenham_n_paths.cpp, so we need to stick with the idea to take step in \(C_max\)(max out of x and y) and then take a step in \(C_min\) (minimum of x and y).
