Net Benefit Optimization track
This track concerns compensating between utility received by achieving soft goals and total cost of the actions used to achieve them. Planners competing in this track are expected to find optimal plans in terms of the objective function. Planners compare on the number of problems they manage to solve optimally within a reasonable amount of time.
Core features: STRIPS, action costs, goal utilities, metric quantities
- Optional features: ADL, derived predicates, durative actions
- Objective function: Maximize total utility - total cost.
Core features are those that will appear in most (if not all) of the domains. So, in order for a planner to have chances to win this track of the competition, all the core features must be supported. However, there will exist some domains that do not require all the core features. A clustering of the domains of this track, together with the fraction of each class in the track, is provided below. The performance of all planners will be assessed in all domains they can run (the details of the evaluation schema will be announced on January 31st).
Optional features concern alternative but equivalent versions of each domain. These features will be used only in cases where they facilitate domain modelling. When several alternative versions of a domain are supported by a planner, it is scored on the version on which it performs best.
Classes of the domains for the Net Benefit Optimization track
- STRIPS, action costs, goal utilities, metric quantities (fraction: about 1/3)
- STRIPS, action costs, goal utilities, no metric quantities (fraction: about 2/3)
