<br> Very good Geoffrey!

Hi guys,<br>
<br>
I finished 4th with my drools-solver implementation of the examination track:<br>
<a href="http://www.cs.qub.ac.uk/itc2007/winner/finalorder.htm" target="_blank">http://www.cs.qub.ac.uk/itc2007/winner/finalorder.htm</a><br>
<br>
There's much to learn from the other implementations for drools-solver.<br>
For example, the winner is also using local search (as are most of the others), but he use meta-heuristics to run 3 phases instead of 1, selects his moves a lot smarter and just basically tweaked his configuration a lot better.<br>
<br>
Surprisingly, I actually got the best overal result on dataset10: it will be interesting to find out why (could be tweaking luck though).<br>
I 'll be identifying the features which drools-solver is missing and incorporating them soon.<br>
Since the end of the competition, the trunk has already gained 10% performance (due to removing shadow facts etc).<br>
<br>
I've also done an implementation of the curriculum course track after the competition ended, in less than 16 workings hours.<br>
The mere development speed, maintainability and runtime performance (after initialization...) of DRL score rules is very very promising.<br><font color="#888888">
