The papers in this volume were presented at the Second Italian Conference onAlgorithms and Complexity, held in February 1994 in Rome. This biannual conference series is intended to present research contributions in theory and applications of sequential, parallel, and distributed algorithms, data structures, and computational complexity. The volume contains four invited presentations and 14 regular presentations selected from 32 submissions, each of which was evaluated by at least four program committee members. The invited presentations are by J. Hartmanis and S. Chari, A. Garg and R. Tamassia, S.C. Sahinalp and U. Vishkin, and M. Yannakakis.
