Compilation flags:

static, context_switching_calls

Implements:

public pseudo_random_protocol

public sampling_protocol

Uses:

list

Remarks:

• Implementation: The backend Prolog compiler built-in random generator is only used for the basic random/1, get_seed/1, and set_seed/1 predicates.

• Portability: B-Prolog, CxProlog, ECLiPSe, JIProlog, Qu-Prolog, and Quintus Prolog do not provide implementations for the get_seed/1 and set_seed/1 predicates and calling these predicates simply succeed without performing any action.
