Re: [robocup-rescue-s] Package Simulationrunner.

Hallo, Nobel,

Thank you for your suggestion. I'm quite not sure whether it will solve my problem or not. As I told, I need to have a Java app controlling the whole process. Here is what I have:

Genetic Algorithm in Java:
> start genetic population
loop
> start simulation
> start agents
> detect end of simulation
> kill remaining simulators
> kill remaining agents
> calculate fitness
> generate new offspring
restart loop

Therefore, I need the Java application (genetic) running, optimizing the agents over and over again. The genetic will be running for more than 10 hours non-stop. That's why I said that I must "repeatedly" start the simulation inside the same Java app. I could write a script that would first start the simulation, then the agents. No problem. But except for the first run, all the next teams of rescue agents being restarted will be based on the genetic offspring, i.e. they need to start only when the genetic says so. Therefore, if sim and team are running independently from the genetic app, I'd have to find a way to synchronize the genetic with the script. It would not be reliable.

That's why I think it's easier to simply have the Java program (the genetic) deciding when to start what, making calls to other processes. So, could I successfully run the all.sh (or similar) from withing Java? Up to now I couldn't. I don't know what I'm doing wrong, or if I should set something. If you developed a package that successfully starts the simulation and that package can be called from a Java app, then it would be really helpful to me! Is this package public? I have no problems running my agents (for they are in Java too), it's only the sim that is giving me trouble to start, to detect when it stops and so on.

Thank you in advance.

On this package there are plenty of classes to support a pure Java control over "starting and stopping" simulation and agents, safely handling most of the common issues. If it's possible to make such call from inside a Java application, then it would be easier for me to control the experiments based in what I have developed so far.
>>>> Nevertheless, I'm not sure whether "simulationrunner" is still compliant with the latest versions of the robocup rescue simulation kernel or else just too old to be so (the header says: Last change: Date: 2004/05/04). If that's the case, I could adapt them to be compatible to the version 0.49 - which I'm using under openSuse. Hence, my questions are:
>>>> Is there anyone who successfully made use of the package "simulationrunner"? If so, did you have to adapt it to the kernel 0.49?>> Is there anyone who already faced the same necessity and came up with a simple solution or developed a package for it?>> Does anyone know where I can find the file "simulation.config", asked as a parameter by the class "StartSimulation"?
