i'm looking research paper or other publication compare different abstract machines (more one) execution of prolog prolog interpreters not based on abstact machines. i've seen far majority of implementations seems base prolog interpreters on warren abstract machine although other abstract machines proposed (eg. vienna abstract machine , tree-oriented abstract machine ) , there no general comparision. i'm interested in comparision of efficiency ( not features), although compared interpreters should allow constraint-logic programming. you can build constraint logic programming on top of ordinary prolog if introduce primitives trailed constraint store , primitives unification hooks. e.g.: sicstus prolog: attributed variables http://sicstus.sics.se/sicstus/docs/3.7.1/html/sicstus_17.html jekejeke minlog: little solver http://www.jekejeke.ch/idatab/doclet/prod/en/docs/15_min/10_docu/02_reference/04_examples/05_solver.html http://www.jekejeke.ch/idatab/docle...
