I have a problem with my 2-opt code to solve the Traveling Salesman Problem… I give a set of points [(x1,y1),…..,(xn,yn)]. Here is my code: def swap(i,j,S): a=min(i,j) b=max(i,j) A=S[a:b+1] A.reverse() S=S[:a]+A+S[b+1:] return(S) def opt_g_bis(S,n): S_bis=S[:] Mod=False for i in range(0,n-2): for j in range(0,n-2) : if j != i-1 and j != i+1: if norme(S_bis[i],S_bis[i+1])+norme(S_bis[j],S_bis[j+1])>norme(S_bis[i],S_bis[j])+norme(S_bis[i+1],S_bis[j+1]): S_bis=swap(i+1,j+1,S_bis) Mod=True if norme(S_bis[i],S_bis[i+1])+norme(S_bis[n-1],S[0])>norme(S_bis[i],S_bis[n-1])+norme(S_bis[i+1],S_bis[0]):…

Python: Successive-over-relaxation (Gauss-Seidel with relaxation) code is not converging

I am trying to implement Quantitative Mobility Spectrum Analysis (QMSA) in Python 2.7 + NumPy + MatPlotLib. QMSA is a tool for analysis of magnetic field-dependent Hall-effect measurements. In a semiconductor, more than one type of carrier (electron or hole) with different concentration and mobility can be found. QMSA can seperate the number of different types of carriers, their density,…
