An Array Grammar Programming System A package of Fortran programs has been developed that permits a user to interactively design and test array grammars. The user can control the rule selection procedure in a derivation or parse, using weighted programming matrices; he also has a choice of instance selection schemes (raster,random, parallel). Examples are given involving array languages consisting of simple geometrical patterns, as well as a language of "neuron pictures." CACM May, 1973 Mercer, A.
