Programming by multiset transformation
Jean-Pierre Banâtre, Daniel Le Métayer · Communications of the ACM · 1993
We present a new formalism called Gamma in which programs are described in terms of multiset transformations. A distinguishing property of Gamma is the possibility of expressing algorithms in a very abstract way, without any artificial sequentiality. The expressive power of the formalism is illustrated through a series of examples chosen from a wide range of domains (string processing problems, graph problems, geometric problems...).
