Problems are sortable by difficulty. Code Chef's practice problems allow you to answer in one of over 50 programming languages as you prepare for its internal or external monthly contests.

Yet, while coding as we know it is indeed facing disruption, the creative, problem-solving essence of computer programming is likely to remain a largely human endeavor for the foreseeable future.

In the present paper a bi-objective integer linear programming problem (BILP) is discussed. The main effort in this work is to effectively implement the ϵ-constraint method to produce a complete set ...
