1 Introduction
The term heuristic is used for algorithms which find solutions among all possible ones ,but they do not guarantee that the best will be found, therefore they may be considered as approximately and not accurate algorithms. These algorithms, usually find a solution close to the best one and they find it fast and easily. Sometimes these algorithms can be accurate, that is they actually find the best solution, but the algorithm is still called heuristic until this best solution is proven to be the best. The method used from a heuristic algorithm is one of the known methods, such as greediness, but in order to be easy and fast the algorithm ignores or even suppresses some of the problem`s demands.
The most important among a variety of topics that relate to computation are algorithm validation, complexity estimation and optimization. Wide part of theoretical computer science deals with these tasks. Complexity of tasks in general is examined studying the most relevant computational resources like execution time and space. The ranging of problems that are solvable with a given limited amount of time and space into well-defined classes is a very intricate task, but it can help incredibly to save time and money spent on the algorithms design.
