[rules-users] Non Spatial Map Reduce
I was reading the blog http://www.optaplanner.org/blog/2014/03/03/CanMapReduceSolvePlanningProblems.html and although the unsuitability of the spatial division of the problem makes sense, I'd like to understand why the problem can't be broken up differently. i.e. why can't any solution be loaded into n separate solvers with 1/nth of the moves, and then send the best solution to all the solvers, and repeat? -- View this message in context: http://drools.46999.n3.nabble.com/Non-Spatial-Map-Reduce-tp4028652.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Long pattern for Nurse Rostering
That does make sense. It sounds like I should be adding the facts as domain objects where the index is available instead of generating them during the solution. I was trying to reuse the existing ShiftType3DaysPattern class from the nursing example, but used more than I should have. The code I have is almost working, but it seems to create plateaus. I can give it a push by stopping the GUI, making some changes, and then restarting. So I'll add another rule to do that on it's own. I feel like I'm building a kludgy house of cards though. -- View this message in context: http://drools.46999.n3.nabble.com/Long-pattern-for-Nurse-Rostering-tp4025432p4025452.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Thanks for the reply. The series of shifts that a Doctor works in my schedule is 15 days straight, but not the same Shift for each of those days.

[rules-users] Long pattern for Nurse Rostering
I'm trying to create a rule for a 15 day pattern. When the patterns uses the same shift for all 15 days, I do this: rule unWanted15DayPattern when $pattern : U15DayPattern( $numberOfDays : numberOfDays, $shiftType : shiftType ) ShiftAssignment( shiftType == $shiftType, $employee : employee, $firstDayIndex : shiftDateDayIndex ) ShiftDate( $firstDayIndex == dayIndex, dayIndex % 15 == 0) //Check for different employee working that shift in the next N days $shiftAssignment : ShiftAssignment( shiftType == $shiftType, employee != $employee, shiftDateDayIndex $firstDayIndex, shiftDateDayIndex $firstDayIndex + 15 ) then insertLogical(new IntConstraintOccurrence(unWanted15DayPattern, ConstraintType.NEGATIVE_SOFT, $pattern.getWeight(), $firstDayIndex)); end But I'm having a hard time figuring out how to do it with different shiftTypes for each day, because it means having to use a loop. Not sure if that makes sense, but it anyone has used a long pattern that stores items in a list/array I'd love to hear how they did it. -- View this message in context: http://drools.46999.n3.nabble.com/Long-pattern-for-Nurse-Rostering-tp4025432.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

[rules-users] shiftAssignment change
I'm trying to write a simple web application that uses much of the code from the NurseRostering example. It all works great except when I try to do a change move after terminating solving. In: DroolScoreDirector.afterVariableChanged() for the ShiftAssignment, I get a null back from this: FactHandle factHandle = workingMemory.getFactHandle(entity); My guess is that it's because it's a different copy of the workingMemory than the entity is coming from, but I'm not sure how to access the correct copy. I'm getting the ShiftAssigment from: NurseRoster nurseRoster = (NurseRoster) solutionBusiness.getSolution(); ListShiftAssignmentshiftAssignmentList=nurseRoster.getShiftAssignmentList(); and then attempting the move from: solutionBusiness.doMove(new EmployeeChangeMove(shiftAssignment, toEmployee)); Is there something else I need to do after terminating solving before doing a changemove? -- View this message in context: http://drools.46999.n3.nabble.com/shiftAssignment-change-tp4023179.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Found solution vs actual optimum [planner]
I ran the benchmarker and it's showing that I should be using simulated annealing. So that's useful info. I'm only getting 525-650 for the average calculate count per second though. (I didn't realize I could get it without the benchmarker until reading the docs again) I'm going through Score calculation performance tricks now, but I didn't see anything about the hardware used for the expected 1000 value.

Better than other algorithms is what I'm after. The output from the sample data sets is excellent. So easy to scan through and understand all the results immediately. Anyone that hasn't used it should give it a try. I'm running the benchmarker on my inputs and rules now. I'm just using the Nurse Rostering example with different inputs and a few more rules, but it's been taking me around 6 hours to get the score I expect. I'm also using planner to try and show cases where an acceptable solution can't be found, and I'll be more confident knowing I'm tried all the methods.
