WebThe hot topic among medicinal chemists today is a novel technique for chemical synthesis in drug research called combinatorial chemistry, where usually a core structure and some building‐block molecules are given and all combinatorially possible combinations are produced. The resulting set of compounds (called a library) can afterwards be … In the mathematical discipline of graph theory, a matching or independent edge set in an undirected graph is a set of edges without common vertices. In other words, a subset of the edges is a matching if each vertex appears in at most one edge of that matching. Finding a matching in a bipartite graph can be treated as a network flow problem.
