Editorial, Volume 32, No. 1, April/May 2019

Welcome to the new issue of your favorite Newsletter.
First of all, on behalf of the entire crew of the ALP Newsletter, we would like to apologize for some of the recent delays in getting the newsletter out. Administrative duties have thrown a temporary wrench in Agostino’s and Enrico’s schedules and for a while things have been a bit crazy. But we are happy to be back on track and ready to provide you with exciting ALP News!!

It is a pleasure for us to introduce the partially renewed ALP Newsletter board that will help us for (at least) a couple of years. They are giving a great service to the ALP community. We enlist and thank them all. For details, see the proper page in this web site:

  • Roman Barták, Andrea Formisano (CLP),
  • João Leite, Matteo Baldoni (MAS),
  • Gerhard Friedrich, Carmine Dodaro (Applications),
  • Fabrizio Riguzzi, James Cussens (ILP),
  • Alessandra Mileo, Francesco Ricca (DB & SW),
  • Martin Gebser, Jose F. Morales (Implementation),
  • Marcello Balduccini, Fangkai Yang  (KR & NMR),
  • Fabio Fioravanti , Samir Genain (Analysis & Verification),
  • Joohyung Lee , Mario Alviano (Foundations),
  • Gian Luca Pozzato (Student Specialist), and
  • Paolo Baldan and Roberto Bruni (Games & Puzzles).

A great thank is due to the friends that have served in the same role for many years, namely: Paolo Torroni, Yuliya Lierler, German Vidal, and Pedro Cabalar.

In this issue, you will find two very interesting articles. The first deals with ASP solving using lazy grounding – a fundamental challenge for many of us; the authors describe a novel solver – the Alpha solver – which might be an answer to such challenge. The second article brings us into the realm of statistical reasoning and machine learning applied to recognition of complex events. The newsletter provides also a conference report from a very successful RuleML+RR Conference.

The preparation for ICLP 2019 is in full swing. The conference will return to Las Cruces after 20 years and the program is shaping up full of new components – please make a point to submit/attend/participate, it will be a fun and engaging conference – and you really don’t want to miss the REAL mexican food!

Cambridge University Press, the publisher of Theory and Practice of Logic Programming, will require the “ORCID iD” of any author (including those that will be accepted to ICLP 2019). So, if you don’t have one yet, please, apply for your (free) ORCID id: https://orcid.org/

In closing, it is always sad to talk about the loss of people that gave so much to our community. A few weeks ago, we received notice of the passing of Ramon Otero. No only Ramon was a fantastic researcher that provided a number of important contributions, but he was also a gentle man with mild manners and a very friendly attitude. I (Enrico) have fond memories of spending time talking to Ramon during his extensive visits in the Southwest (Las Cruces in 1995 and El Paso in 2000). Ramon will be missed and, on behalf of the entire ALP team, we would like to express our most sincere condolences to his family. I (Agostino) would like to express my personal condolescences and those of the Italian association of logic programming.
