Support real-time problem modification during solving with utils for the single thread subsystem ------------------------------------------------------------------------------------------------ Key: JBRULES-680 URL: http://jira.jboss.com/jira/browse/JBRULES-680 Project: JBoss Rules Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Solver Reporter: Geoffrey De Smet Assigned To: Geoffrey De Smet Rete/Drools is single threaded, and so is the current implementation of the localsearchsolver, but this single thread subsystem should be documented and utils should be provided to allow for real-time problem modification A simple way would be to use a producer-consumer pattern with a non blocking queue which holds "problem moves". Each step the problem moves could be used. Problems: - bestsolutionrecalled also needs it's score adjusted. so we'll need a 2th working memory: -- EITHER temporary, just for the problem move (or set of problem moves) -- EITHER all the time, but then we'd have to hold a chain of moves, some of which might not be doable at the end - cached selectors must be notified of refreshing their cache - solution cloning normally doesn't clone the problem facts, just the proposed solution references. Do we need a full clone now? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
