This book constitutes the proceedings of the 20th

International Conference on Logic for Programming, Artificial Intelligence, and

Reasoning, LPAR-20, held in November 2015, in Suva, Fiji.







The 43 regular papers presented together with 1 invited

talk included in this volume were carefully reviewed and selected from 92

submissions. The series of International Conferences on Logic for Programming,

Artificial Intelligence and Reasoning, LPAR, is a forum where, year after year,

some of the most renowned researchers in the areas of logic, automated

reasoning, computational logic, programming languages and their applications

come to present cutting-edge results, to discuss advances in these fields, and

to exchange ideas in a scientifically emerging part of the world.
