(A fuller description will be available soon.)
Version 0.8 (and up) supports nondeterministic execution mode that explores all possible reduction paths.
By specifying the -nd option to lmnr(_cyg), the system computes all possible reduction paths and displays the reduction graph (a graph representing all possible states and state transition). A powerful feature of the nondeterministic execution mode is that it will return a finite cyclic graph for a diverging program as long as the set of all possible states is finite.
By specifying both the --interactive option and the -nd option, the system displays possible results (= final states) of execution one by one in response to the ";" characters entered by the user (as in Prolog systems).
The system comes also with the "all solutions" feature. The process
nd.exec{ { ... LMNtal program here ... }* }
will be reduced to a reduction graph of the (Flat) LMNtal program enclosed by the double membranes.
