Graph rewrites, from graphic lambda calculus, to chemlambda, to directed interaction combinators

Here I report about the modifications of and relations between graphic lambda calculus, various formalisms which appeared under the name chemlambda and a version of directed interaction combinators. This is part of the study and experiments with the artificial chemistry chemlambda and the relations with lambda calculus or interaction combinators, as described in arXiv:2003.14332 and available from the entry page at https://chemlambda.github.io/index.html
