Prolog systems typically implement a well-known optimization technique called tail call optimization (TCO) for deterministic predicates exhibiting tail recursion or, more generally, tail calls: A clause's stack frame is discarded before performing a call in a tail position. The disadvantage of such failure driven loops is that possibly failure of the process predicate does not abort the loop and thus is easily missed. See also - between/3.

Code block is executed multiple times using recursive predicate logic. 2009-12-07 · Unlike java, which has for-loops facilities to enable a set of instructions to be executed a fixed numbers of times, PROLOG is unavailable to do that (directly), but a similar effect can be obtained using recursion, such as : testloop(0).

Prolog for loop

1. Looping a Fixed Number of Times In the Prolog program, the easiest way to provide the type of looping is not always recursion. Another method to provide the looping is built-in predicate repeat. The goal repeat does not mean that it repeats anything. Whenever it called, it merely succeeds. The ECLiPSe language (which basically is a variant of Prolog) has a do/2 predicate which is used to build loops. Using loops in Prolog code is sometimes useful, since it leads to more readable code that is also easier to change.

edu 1 [email The predicate forall/2 is implemented as \+ ( Cond, \+ Action), i.e., There is no instantiation of Cond for which Action is false.. The use of double negation implies that forall/2 does not change any variable bindings. It proves a relation. The forall/2 control structure can be used for its side-effects.
