This book constitutes the refereed proceedings of the 5th International Conference on Verification, Model Checking, and Abstract Interpretation, VMCAI 2004, held in Venice, Italy in January 2004.The 22 revised full papers presented together with 4 invited contributions were carefully reviewed and selected from 68 submissions. The papers are organized in topical sections on security, formal methods, model checking, software checking, liveness and completeness, and miscellaneous.

This volume constitutes the proceedings of the Fourth International Conference on Algebraic and Logic Programming (ALP '94), held in Madrid, Spain in September 1994.
Like the predecessor conferences in this series, ALP '94 succeeded in strengthening the cross-fertilization between algebraic techniques and logic programming. Besides abstracts of three invited talks, the volume contains 17 full revised papers selected from 41 submissions; the papers are organized into sections on theorem proving, narrowing, logic programming, term rewriting, and higher-order programming.
