Introduction-completeness, reductions, approximations which are used to answer this refined question. We present these concepts from the viewpoint of logic, called descriptive complexity and emphasize the roles of randomness and approximation.

Introductiontists and the new ideas brought by the theory of complexity. Given a problem, it is important to know if there is an algorithmic solution, i.e, if the problem can be solved by an automatic procedure based on a finite set of instructions .

Deduction systems on a refutation: we suppose that the formula is false and we try to show a contradiction. The method consists in the construction of a tree whose nodes are labelled by sets of formulas. For this construction, it uses rules taking into account the structure of the formulas. These rules are dual of .作者: HACK 時間: 2025-3-24 23:18 作者: B-cell 時間: 2025-3-25 04:55
