Windows/cross-platform support?
|
| |
Hello, Have there been any efforts to build the LAMA planner for Windows? We are using it in a larger planning tool currently -- but most of our end-users use Windows. I've tried to compile the current codebase using mingw, but there appear to be some quirks that are causing LAMA to fail to build.... more »

I was working on the best-first search component of LAMA when I learned that FD is where the on-going development is happening. But I cannot see an obvious best-first search implementation in FD such as there is in LAMA... more »

Required vs Suggested Landmarks
|
| |
Hi, Has anyone had experience with forcing LAMA to satisfy landmarks (or particular disjuncts of a landmark)? As far as I understand it, the landmark count heuristic "suggests" that the search satisfy landmarks, but there is no facility to prune plans that fail to satisfy a landmark. Thanks in advance!... more »

lab 1.2 news

Hi everyone,
since the last release the experimentation framework lab has seen a lot of improvements. Some highlights are:
* Reparse an experiment directory in case you forgot to extract some
values from the log.
* The "compact" parameter for DownwardExperiments now makes the
experiments even more compact and during execution temporary files... more »
