Abstract :
ET is a complete evaluation strategy for pure logic programs. The ET algorithm is an essentially depth-first strategy that uses extension tables, which save the answers of selected predicates, to evaluate (recursive) declarative specifications. The implementation of the ET algorithm in Prolog is straightforward and easily modifiable. The author presents variations of the ET algorithm that, under certain assumptions, improve the evaluation of declarative specifications.<>
