Monitoring the Execution of Partial-Order Plans via Regression

Article reviews

Este articulo, consiguen las condiciones en las que un POP continua siendo viable (ejecutable) por medio de la regression de los goal a través de la estructura de un POP.

Temporal relaxed planning graph (TRPG)

TRPG is employed in CRIKEY3. The durative actions are splitting into start and end snap-actions, possitive and negative effects, respectively.

There are several reasons why the execution of a plan may fail, whether internal (the execution of an action fails) or external (changes in the world, damaged or add objects, etc). If we go to temporals plans, the factors may be much larger and more delicate, such action runs faster or slower than expected.

Classical planning and new approaches

"Classical AI planning is concerned with the generation of plans to achieve a set of pre-defined goals in situations where most relevant conditions in the outside world are known, and where the plan's success is not affected by changes in the outside world" Qiang Yang.

Visiting the Roque de los Muchachos

I was visiting the Roque de Los Muchachos Observatory from 6-7 Aug. It was awesome !

The Accountant

Recently, I participate in the awesome coding contest The Accountant in CodinGames. This contest was a 2-week optimization challenge, where it was not necessary to succeed all of the given test cases to have a good score. Unfortunately, I didn't use the 2 week because I was travelling. I only used 5 days.

It was my second time in this kind of contests, and I finished in the position 1774/6214 ( you can see the report in The Accountant report for my user cguzman ). Not so bad for a second time :)

I am not an expert in Genetic Algorithm (GA), but I decided to implement one for this solution. Thus, now I will explain how was my approach for this challenged.

cguzman

After graduating at the University of San Buenaventura Cartagena de Indias (Colombia), I traveled to Germany at the University of Heidelberg to learn German. I was joined as a Master candidate at University Politécnica of Valencia (Spain) at 2007. My master thesis in Computer Science was finished in 2009 with Dr. Eva Onaindia as my advisor. Next, I continued with my Ph.D. dissertation, which I finished at 5th april 2019. My main research interests are planning and scheduling, reactive planning in multi-agent systems, coordinate the plan execution of several agents, execution, monitoring, decision support for repairing and re-planning focused on any aspect of real life. I love the science and the space !
