combination_lock, a Fortran77 code which simulates the process of determining the combination of a lock.
This program demonstrates the method of exhaustive search, that is, it searches for an answer by trying every possibility. This requires a way of logically ordering the possibilities.

combination_lock is available in a C version and a C++ version and a Fortran77 version and a Fortran90 version and a MATLAB version.
change_making, a Fortran77 library which considers the change making problem, in which a given sum is to be formed using coins of various denominations.
COMBO, a Fortran90 library which includes many combinatorial routines.
KNAPSACK_01, a Fortran77 library which uses brute force to solve small versions of the 0/1 knapsack problem;
PARTITION_PROBLEM, a Fortran77 library which seeks solutions of the partition problem, splitting a set of integers into two subsets with equal sum.
SATISFY, a Fortran77 program which demonstrates, for a particular circuit, an exhaustive search for solutions of the circuit satisfiability problem.
SUBSET, a Fortran77 library which enumerates combinations, partitions, subsets, index sets, and other combinatorial objects.
SUBSET_SUM, a Fortran77 library which seeks solutions of the subset sum problem.
TSP_BRUTE, a Fortran77 program which reads a file of city-to-city distances and solves the traveling salesperson problem, using brute force.
