摘要: Suppose you want to find the solution S a mathematical problem in some domain. Depending upon type of operations under consideration that lead construction S, one can distinguish between "pure mathematics" (which uses tools such as infinite union, limits, etc.) and "algorithmic (whose are substitution, if-then-else, recursion, etc.). Algorithmic mathematics is interested only those solutions be expressed by constructs whose effects realized (idealized) machines. Hence, essence algorithmic solving hinges on realization "relative" given "black box" (i.e. idealized machine) operations.
