============================== Optaplanner Devconf workshop 2015 ==============================

--- TASK 1 ---
1. open project in java IDE you've selected (just click on parent pom.xml)
2. open module called cloudbalance-easymodel
3. search for src/main/java/org/optaplanner/examples/cloudbalancing/domain package and get familiar with java classes
   3a. which are planning entities and what are their variables?
   3b. where they get values for variables?

--- TASK 2 ---
4. open src/main/resources/org/optaplanner/examples/cloudbalancing/solver/cloudBalancingSolverConfig.xml 
5. execute run_easy.sh (or run_easy.bat), pick "15 computers with 45 processes" scenario and see what planner does
   - graphic output (very fast, you may miss it)
   - see log in terminal 
6. try to uncomment "localsearch" section in cloudBalancingSolverConfig.xml and do step 5. again
7. observe the score difference
   7a. why is score better?
   7b. is there possibility that score after localsearch phase is not better? and why?  

--- TASK 3 ---
8. open module called cloudbalance-sophisticated
9. search for src/main/java/org/optaplanner/examples/cloudbalancing/domain package and get familiar with java classes
   9a. there are extra annotations
   9b. there are extra files (comparators) - why do we need them? see in code 
   9c. run construction heuristic only and compare time and score differences with TASK2
       - config file: src/main/resources/org/optaplanner/examples/cloudbalancing/solver/cloudBalancingSolverConfig.xml
10. search for src/main/java/org/optaplanner/examples/cloudbalancing/solver/score 
   10a. check EasyScore score function and IncrementalScoreFunction
       - why do we need incremental score function?
   10b. in cloudBalancingSolverConfig.xml try speed difference between easy and incremental score calculation

--- TASK 4 --- (optional)
11. pick one score calculation and add a new hard constraint: no computer should have more than 4 processes assigned to it
   - note: incremental and map based scoreFunctions are harder for implementation
