Mathematica programs for minimizing the function W under the energy constraint H = E

contours Minimizing the function W, the main program that calls sub-programs
contchec Printing input parameters and checking their validity
contnumb Finding extrema and choosing the global minimum
contplot Density plot of functions with display of the minimum
printing Package for formatted printing of numbers

Example of usage of these programs

omx = 0.9; omy = 1.1;
x0 = 0.1; y0 = 0.2;
h30 = -0.1; h21 = 0.3; h12 = 0.2; h03 = 0;
w30 = 0.05; w21 = 0.05; w12 = 0.05; w03 = -0.05;
h40 = h31 = h22 = h13 = h04 = 0;
w40 = w31 = w22 = w13 = w04 = 0;
