'''Algorithmics''' is the science of [[algorithm]]s. It includes [[algorithm design]], the art of building a procedure which can solve efficiently a specific problem or a class of problem, [[algorithmic complexity theory]], the study of estimating the hardness of problems by studiyng the properties of algorithm that solves them, or [[algorithm analysis]], the science of studying the properties of a problem, such as quantifying ressources in time and memory space needed by this algorithm to solve this problem.
