CG_RC is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version and a Python version.
BACKTRACK_BINARY_RC, a FORTRAN90 library which carries out a backtrack search for a set of binary decisions, using reverse communication.
BISECTION_RC, a FORTRAN90 library 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.
CG, a FORTRAN90 library 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.
