If your problem is A* search efficient, you should use A* search. It's
better and simpler than any metaheuristic.
Problem is, most real-life problems are NP complete and A* search
doesn't work efficiently on those.
Some examples:
- Quickest route between 2 cities: Use A* search
- Quickest route
Thanks for reply.. Laune
There are things in the book that would answer some questions..
Well, it's good to know that I can express a Heuristic Knowledge in Drools
Expert.
And I have drools planning to use metaheuristic.. But, I need to model my
problem well first to know what approach I will
Hi sotty.. I know how A* algorithm works, but it's only a theoretical
knowledge..
It's good to know that I can express Heuristic Knowledge using drools
rules..
I just need to adjust well the problem domain to know what I really need to
do..
Thanks for showing how to use an heuristic behavior
Hi Daniel, if you have predictive models you might be interested in the PMML
integration we're working on.. but it's indeed necessary that you define the
nature of your problem and your requirements first :)
Let us know if you need more assistance

Hi Geoffrey..
Thanks for reply..
I'm brainstorming the biologist's Knowledge domain..
maybe heuristic approach could be the solution or I can do it in a simple
way..
But for now,. I have just rules with different ways to use them.. specific
for each biologist.
The Idea is to mix them to have an
Even more i read things seems more complex that are.. but in the same way
seems not..
I partially read about PMML and the following model seems a good solution:

If I have facts mined expecting some value to show how
Predictive models, such as neural networks, support vector machines, cluster
models, decision trees etc can be used in two ways. One is classification:
you take some input data/facts and the model will estimate if this
particular set has a given characteristic or not.
E.g. given a set of genes,
Hi Sotty.. It's ok..
Here you can find something about my project that I run into.. BioAgents

First it started using JESS.. after that Drools and Reinforcement Learning..
But the method applied
Did you really send a 50k rows table to a personal email ??? I can't believe it
...
I think you should :
- read the mailing list rules
- read the previous Wolfgang post telling that you should consider not using
such big tables (consider a rule using your 50k rows as parameters)
- ask
Relax, Vincent, it was sent due to my explicit request, and it was a maller
size version.
I've taken this off-list to get a first-hand impression of why these DTs
are considered as a viable solution, and how it fails, etc.. And I think
that the OPs Q is legitimate; techniques propagated in Drools
ok sorry ...
may be one idea then: drools is using POI as java layer to read xls sheets, and
it is very very very memory consuming ... especially with .xlsx format. May be
that drools parser don't even reach a point where it can check the row count
...
hope this helps... sorry again .

this can be avoided using proper unzip tools. If any have this issue use
winrar/winzip or any unzip tool.
I used windows xp to unzip the file, that's why i got that error.

Hi,
In the cloudbalance example...I noticed two comparator classes...
CloudProcessDifficultyComparator (this is for planning entity class
comparator) and CloudComputerStrengthComparator (this is for planning
variable comparator class),
please help me to understand more about these planning
