<p><b>Abstract</b>—In this paper, we present efficient algorithms for sorting, selection, and packet routing on the AROB (Array with Reconfigurable Optical Buses) model. One of our sorting algorithms sorts <it>n</it> general keys in <it>O</it>(1) time on an AROB of size <tmath>$n^\epsilon \times n$</tmath> for any constant <tmath>$\epsilon > 0.$</tmath> We also show that selection from out of <it>n</it> elements can be done in randomized <it>O</it>(1) time employing <it>n</it> processors. Our routing algorithm can route any <it>h</it>-relation in randomized <it>O</it>(<it>h</it>) time. All these algorithms are clearly optimal.</p>
