> This paper presents some fundamental properties of independent and-par-allelism and extends its applicability by enlarging the class of goals eligible for parallel execution. A simple model of (independent) and-parallel execution is proposed and issues of correctness and eeciency discussed in the light of this model. Two conditions, \strict" and \non-strict" independence , are deened and then...
