41Outline of chemistry — The following outline is provided as an overview of and topical guide to chemistry: Chemistry – science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties,… …
42Pseudoforest — A 1 forest (a maximal pseudoforest), formed by three 1 trees In graph theory, a pseudoforest is an undirected graph[1] in which every connected component has at most one cycle. That is, it is a system of vertices and edges connecting pairs of ve …

48Incidence structure — In combinatorial mathematics, an incidence structure is a triple :C=(P,L,I)., where P is a set of points , L is a set of lines and I subseteq P imes L is the incidence relation. The elements of I are called flags. If :(p,ell) in I,we say that… …
49Algorithm characterizations — The word algorithm does not have a generally accepted definition. Researchers are actively working in formalizing this term. This article will present some of the characterizations of the notion of algorithm in more detail. This article is a… …
50Guided Local Search — is a metaheuristic search method. A meta heuristic method is a method that sits on top of a local search algorithm to change its behaviour. Guided Local Search builds up penalties during a search. It uses penalties to help local search algorithms …
