[rules-users] Problem using KnowledgeAgent
I setup a KnowledgeAgent using the example code in the JavaDoc for KnowledgeAgentFactory to access a compiled package in Guvnor. The package runs fine, but changes to the package are not picked up. I believe this is due to the ChangeSet notification thread being interrupted. But why? Also, I'm getting some messages about failing to read schema document. I think it is caused by the xml for the ChangeSet, but I'm using the example from the JavaDocs. Here's a snippet from the log: [2009:02:48 23:02:905:info] KnowledegAgent has started listening for ChangeSet notifications [2009:02:48 23:02:905:info] KnowledgAgent created, with configuration: monitorChangeSetEvents=true scanResources=true scanDirectories=true [2009:02:48 23:02:905:exception java.lang.RuntimeException: KnowledgeAgent ChangeSet notification thread has been interrupted at org.drools.agent.impl.KnowledgeAgentImpl$ChangeSetNotificationDetector.run(KnowledgeAgentImpl.java:465) at java.lang.Thread.run(Unknown Source) Caused by: java.lang.InterruptedException at java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.reportInterruptAfterWait(Unknown Source) at java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.await(Unknown Source) at java.util.concurrent.LinkedBlockingQueue.take(Unknown Source) at org.drools.agent.impl.KnowledgeAgentImpl$ChangeSetNotificationDetector.run(KnowledgeAgentImpl.java:463) ... 1 more [2009:02:48 23:02:937:info] KnowledegAgent has stopped listening for ChangeSet notifications (null: 1, 207): schema_reference.4: Failed to read schema document 'drools-change-set-5.0.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not xsd:schema.

[rules-users] Rule Templates and Guvnor

Hi, You can't use templates at the moment. But you can use the copy function in the rule editor. Create a rule that is used as a base, disable it and copy this rule when creating new ones.

RE: [rules-users] Rule Templates and Guvnor
Hi Tony, We were actually looking to use Templates because our clients objected to having code or pseudo-code in an Excel along with the data. Templates, seem an excellent feature where the code bits can be separated from the data bits. One thought I had was to store the templates in the other assets part of Guvnor and the data as well and somehow write something that can pull these out at run-time and create and compile the rules. However, we do loose all the other functionality that Guvnor provides.(Like rule analysis etc). Any idea, if Guvnor is going to support templates in a future release?

Hi,
Thanks for the rules suggestions, using a simple generated id has
radically improved my solver times (and my scoring).
It surprises me that generated id's radically improve solver times.
Could you give an example of what you changed?
relativeSelection should radically improve solver times, if tweaked
correctly.
I'm now looking
into using the StartingSolutionInitializer code to feed
startingSolutions into the solver.
I'm a little confused about the intended functionality in the interface,
and wanted to get some feedback. Basically, the simple solver that we
had used previously to find our solution space, didn't take into account
any of the topographical constraints of our game board. The solutions
it offered are not highly specific, in the sense that one doesn't know
where all the tokens should be placed. What it does offer are
distributions of tokens on the game board. For example:
4 tokens of managed forest per territory.
4 tokens of moderate pasture per territory.
4 tokens of intensive pasture per territory.
I'd like to use the startingSolutionInitializer to take a suggested
distribution, populate our board with those values, and then pass it
back to the solver to solve.
For that you don't really need a startingSolutionInitializer, you could
just set that solution directly as the starting solution on the solver.
A startSolutionInitializer has the advantage that it can reuse the
instance of the working memory with the score rules to initialize the
starting solution.
Is the initializer the right place to do this? Or should I simply view
the initializer as a deterministic entry point for ordering and
composing an incomplete solution before passing it off to the solver?
best wishes,
Andrew

Hi,
I've been looking through my solver logs and on a problem i have
posed, the solver seems to first initialize and setup a best score:
INFO: Initialization time spend (3) for score (-504.0). Updating
best solution and best score.
However, this score is not correct. I use collect to load Tokens of
a certain type for my game, and those that are found, penalize the
system with a constraint:
rule Too much unclaimed territory
when
$list : ArrayList ( size 2) from collect (
Token ($type : type == TokenType.UNDEVELOPED))
then
for (int i = 0; i $list.size(); i++) {
insertLogical (new IntConstraintOccurrence (
Too much unclaimed territory,
ConstraintType.NEGATIVE_SOFT, 3, $list));
Doesn't this insert the same logical fact in a loop? So only 1
instance actually remains in the working memory?
If you want to have to list.size() affect the score, just do:
3 * list.size()
}
end
Why use collect anyway?
when
$t1 : Token ($type : type == TokenType.UNDEVELOPED, id1 : id)
$t2 : Token ($type : type == TokenType.UNDEVELOPED, id id1,
id2 : id)
$t3 : Token ($type : type == TokenType.UNDEVELOPED, id id2,
id3 : id)
// maybe you need things like this: not Token ($type : type ==
TokenType.UNDEVELOPED, id id3)
then
insertLogical (new IntConstraintOccurrence (Too much unclaimed
territory, ConstraintType.NEGATIVE_SOFT, 3, $t1, $t2, $t3));
However, the initial score does not seem to account for these
inserted facts. Due to this, all improving solutions are rejected,
and I see no change in the solution the solver finds and my starting
solution. Any suggestions on how to delay initialization? Or get
the starting score to take into account this constraint (I've made it
SOFT so the values aren't so hard to follow in the logs, it was
initially a HARD constraint). I'd love to find a way around this
problem, I've spent most of the day playing with different
configurations (acceptors and foragers) trying to find a
configuration that works for this base problem.

Andrew

Re: [rules-users] Re: drools-solver [StartingSolutionInitializer]
Hi Geoffrey,
Before, I was simply using a string id, based upon row and column.
Now I've implemented a simple generator for an integer based id. This
has helped my scoring, as the same two tokens are only matched once,
in order, as opposed to being matched twice (or even three times).
This makes my scores much easier to understand, and was a great help
with debugging my constraints. Speed seems to have gone up some, as
the tree doesn't have to double or triple match tokens in
workingmemory, but I can't vouch for this as only now are my puzzles
being solved properly.
I see your point with regards to the startingSolutionInitializer --
I've moved on today to building some simple configurators for the
problems I wish to check based on XML (using Jdom). Thanks for all of
your input and help through this process; I'm immensely pleased with
the end result and will work to pass on feedback as I continue to use
the tool.
best wishes,
Andrew

Hi,
Thanks for the rules suggestions, using a simple generated id has
radically improved my solver times (and my scoring).
It surprises me that generated id's radically improve solver times.
Could you give an example of what you changed?
relativeSelection should radically improve solver times, if tweaked
correctly.
I'm now looking
into using the StartingSolutionInitializer code to feed
startingSolutions into the solver.
I'm a little confused about the intended functionality in the
interface, and wanted to get some feedback. Basically, the simple
solver that we had used previously to find our solution space,
didn't take into account any of the topographical constraints of
our game board. The solutions it offered are not highly specific,
in the sense that one doesn't know where all the tokens should be
placed. What it does offer are distributions of tokens on the game
board. For example:
4 tokens of managed forest per territory.
4 tokens of moderate pasture per territory.
4 tokens of intensive pasture per territory.
I'd like to use the startingSolutionInitializer to take a suggested
distribution, populate our board with those values, and then pass
it back to the solver to solve.
For that you don't really need a startingSolutionInitializer, you
could just set that solution directly as the starting solution on
the solver.
A startSolutionInitializer has the advantage that it can reuse the
instance of the working memory with the score rules to initialize
the starting solution.
Is the initializer the right place to do this? Or should I simply
view the initializer as a deterministic entry point for ordering
and composing an incomplete solution before passing it off to the
solver?
best wishes,
Andrew

Hi,
I've been looking through my solver logs and on a problem i have
posed, the solver seems to first initialize and setup a best score:
INFO: Initialization time spend (3) for score (-504.0).
Updating best solution and best score.
However, this score is not correct. I use collect to load Tokens
of a certain type for my game, and those that are found, penalize
the system with a constraint:
rule Too much unclaimed territory
when
$list : ArrayList ( size 2) from collect (
Token ($type : type == TokenType.UNDEVELOPED))
then
for (int i = 0; i $list.size(); i++) {
insertLogical (new IntConstraintOccurrence (
Too much unclaimed territory,
ConstraintType.NEGATIVE_SOFT, 3, $list));
Doesn't this insert the same logical fact in a loop? So only 1
instance actually remains in the working memory?
If you want to have to list.size() affect the score, just do:
3 * list.size()
}
end
Why use collect anyway?
when
$t1 : Token ($type : type == TokenType.UNDEVELOPED, id1 : id)
$t2 : Token ($type : type == TokenType.UNDEVELOPED, id
id1, id2 : id)
$t3 : Token ($type : type == TokenType.UNDEVELOPED, id
id2, id3 : id)
// maybe you need things like this: not Token ($type : type ==
TokenType.UNDEVELOPED, id id3)
then
insertLogical (new IntConstraintOccurrence (Too much unclaimed
territory, ConstraintType.NEGATIVE_SOFT, 3, $t1, $t2, $t3));
However, the initial score does not seem to account for these
inserted facts. Due to this, all improving solutions are
rejected, and I see no change in the solution the solver finds
and my starting solution. Any suggestions on how to delay
initialization? Or get the
[rules-users] Annotation-Defined POJO Rules?
Found this page here which describes how to write POJO rules: http://docs.codehaus.org/display/DROOLS/Drools+Spring+Tutorial Neat!
