Abstract: "This paper considers a multikey search problem for implicit data structures. More specifically, n k-key items (k a constant) are to be stored in a k-by-n array (one item per column) so that given a key the corresponding item can be found efficiently. We present two algorithms for this problem. One takes O(log n) time, which matches the complexity of the previous optimal but more complicated algorithm of Fiat et al. The other algorithm takes time O(log℗n) for a search, but the multiplicative constant is smaller so that its performance is better than that of the O(log n) algorithms as long as n is not unreasonably large."
