For-loops in Logic Programming

Abstract

Logic programming has traditiLogic programming has traditionally lacked devices for expressing iterative tasks. To overcome this problem, this paper proposes iterative goal formulas of the form $\seqandq{x}{L} G$ where $G$ is a goal, $x$ is a variable, and $L$ is a list. $\seqandq{x}{L}$ is called a parallel bounded quantifier. These goals allow us to specify the following task: iterate $G$ with $x$ ranging over all the elements of $L$. onally lacked devices for expressing iterative tasks.
