The ALP Alain Colmerauer Prize

The ''ALP Alain Colmerauer Prize'' (in short: ''Alain Colmerauer Prize'') is organized by the Association for Logic Programming. The Prize is given for recent accomplishments and practical advances in Prolog-inspired computing, understood in a broad sense, where foundational, technological, and practical contributions are eligible with proven evidence or potential for the future development of Logic Programming. The award of the inaugural edition of the Prize in 2022, in cooperation with the Prolog Heritage Association, was a highlight of the Year of Prolog celebrating 50 years of Prolog and logic programming.
