Is there a way to access your own utility weights?

[jogrundy]

I can see the weights in the party domain xml file, but do I have to parse this file to access the weights or is there a better way?
Cheers, Jo

Hi Jo,

You must access weights of each issue via Genius API.

Can you try this and let me know whether this works:

AbstractUtilitySpace utilitySpace = info.getUtilitySpace();
AdditiveUtilitySpace additiveUtilitySpace = (AdditiveUtilitySpace) utilitySpace;

List<Issue> issues = additiveUtilitySpace.getDomain().getIssues();

for (Issue issue : issues) {
    System.out.println(additiveUtilitySpace.getWeight(issue.getNumber()));
}

There can be different types of utility spaces, in this coursework (also in the international competition ANAC), AdditiveUtilitySpace is used.

Hi Taha I got this error message when trying to build, after making sure both abstract and additive utility space were imported: Error:(84, 45) java: info has private access in negotiator.parties.AbstractNegotiationParty Error:(87, 14) java: cannot find symbol symbol: class Issue location: class ExampleAgent Error:(89, 14) java: cannot find symbol symbol: class Issue location: class ExampleAgent where lines 84 - 91 were the lines pasted in to otherwise working code. I’m trying to work around it now.. Jo

@DoctorJo make sure info is accessible. For example:

[jogrundy]

I got this to work AdditiveUtilitySpace additiveUtilitySpace = (AdditiveUtilitySpace) utilitySpace; List<Issue> issues = additiveUtilitySpace.getDomain().getIssues(); for (Issue issue : issues) { System.out.println(additiveUtilitySpace.getWeight(issue.getNumber())); } after making sure I imported negotiator issue.Issue .. as it did not seem like AbstractUtilitySpace was used.. Thank you very much for your help again! Jo

No worries, glad to hear that it works. I'll add this to wiki.
