Combining an improvement to PARMA trailing with trailing analysis


Trailing of bindings in the PARMA variable representation is expensive in time and space. Two schemes are presented that lower its cost: the first is a technique that halves the space cost of trailing in PARMA. It can be used with conditional and unconditional trailing. It is illustrated and evaluated in the context of dProlog and in the Mercury backend of… (More)
