We next discuss several issues on trying to make Prolog programs run
|
|
fast in YAP. We assume two different programming styles:
|
|
|
|
+ Execution of <em>deterministic</em> programs ofte
|
|
n
|
|
boils down to a recursive loop of the form:
|
|
|
|
~~~~~
|
|
loop(Env) :-
|
|
do_something(Env,NewEnv),
|
|
loop(NewEnv).
