backtrack_binary_rc, a python code which carries out a backtrack search for a set of binary decisions, using reverse communication (rc).
bisection_rc, a python code which seeks a solution to the equation f(x)=0 using bisection within a user-supplied change of sign interval [a,b]. the procedure is written using reverse communication (rc).
cg, a python code which implements a simple version of the conjugate gradient (cg) method for solving a system of linear equations of the form a*x=b, suitable for situations in which the matrix a is positive definite (only real, positive eigenvalues) and symmetric.
jacobi, a python code which implements the jacobi iteration for solving symmetric positive definite (spd) systems of linear equations.
