Editorial, March/April 2015

Dear LP friends,

welcome to another issue of the ALP newsletter. We are moving quick towards another ICLP (this time, in fascinating Ireland – we believe a first for the ICLP series). The event will join forces with CP, a proven collaboration that has been often beneficial in the past. We hope you will contribute to this great event and help us making it a success.

We have a rich issue, with very interesting contributions. The article by Mantadelis and Janssens provides a very nice overview of the MetaProbLog framework, a nice contribution to the great work on ProbLog. Surynek provides a technical contribution concerning novel encodings of the all-different constraint suitable to be solved using SAT solvers. The paper by Aziz and colleagues provides another perspective on a topic that has been gaining a strong traction – i.e., the intersection between ASP and CP.

Last but not least, Bob Kowalski has provided an amazing memory from the past, bringing us back in time to the beginning of the logic programming community.

Apart from the content of this issue of the Newsletter, we would like to anticipate a new initiative that will develop over the coming weeks. There has been an intense discussion within the ALP Executive Committee concerning the publication structure of ICLP. We felt the time is right to bring the community up to speed on the existing process, the motivations that led to it, and some of the challenges that we are facing. The goal is to set the stage for a community-wide discussion, that will hopefully inform how this publication structure will evolve to better serve the needs of the logic programming researchers.

An important note by TPLP editor in chief Mirek Truszczynski. To help improve the discoverability of the journal content, Cambridge has partnered with Kudos to offer every author online tools to enable them to increase the visibility and impact of their work. Therefore, any author will receive an e-mail from Kudos shortly after the publication of his/her article inviting him/her to follow a unique link to register and claim their work.

In this issue we would also like to pause and remember a colleague and friend that left us – German Puebla. German was an outstanding researcher who greatly contributed to the field of Logic Programming – his solar attitude was a staple at many logic programming conferences and he will be missed. On behalf of the Newsletter editorial team, we would like to express our most sincere condolences to his family and friends.
