</div><div><br></div><div><br></div><div></div><div>Organized by the Association for Logic Programming</div><br>In the summer of 1972, Alain Colmerauer and his team in Marseille developed and implemented the first version of the logic programming language Prolog. Together with both earlier and later collaborations with Robert Kowalski and his colleagues in Edinburgh, this work laid the practical and theoretical foundations for the Prolog and logic programming of today. Prolog and its related technologies soon became key tools of symbolic programming and Artificial Intelligence.<br><br>2022 was celebrated as the Year of Prolog to recognize the 50th anniversary of these events and highlight the continuing significance of Prolog and Logic Programming both for symbolic, explainable AI, and for computing more generally. The celebration inaugurated the ALP Alain Colmerauer Prolog Heritage Prize (in short: the Alain Colmerauer Prize). 2025 marks the fourth awarding of the Alain Colmerauer Prize.<br><br>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.<br><br><div><b>The 2025 Award</b></div><div><b><br></b></div>Nominations are sought for the 2025 edition of the Alain Colmerauer Prize.<br><br><div><b>Eligibility</b></div><div><b><br></b></div>Any individual or group of individuals can nominate themselves or their institution(s)/organization(s) for the Prize.
