This book celebrates the 25th anniversary of GULP—the Italian Association for Logic Programming. Authored by Italian researchers at the leading edge of their fields, it presents a state-of-the-art survey of logic programming, making it a useful reference for both researchers and students. The volume contains 14 invited papers, each giving a detailed analysis of a specific field of logic programming and providing both a historical perspective and a precise discussion of current research. The book closes with a chapter reviewing in detail the main applications of logic programming developed in Italian researchers in the last 25 years, illustrating successful work done and potential directions for future developments.
