[JBoss JIRA] Created: (JBRULES-1232) [solver] Selector refactor: configurable subset selections, topList usage etc

by Geoffrey De Smet (JIRA)

[solver] Selector refactor: configurable subset selections, topList usage etc ----------------------------------------------------------------------------- Key: JBRULES-1232 URL: http://jira.jboss.com/jira/browse/JBRULES-1232 Project: JBoss Rules Issue Type: Task Security Level: Public (Everyone can see) Components: Solver Reporter: Geoffrey De Smet Assigned To: Geoffrey De Smet Currently all moves are evaluated at every step (with a MaxAllForager at least) if you use the basic cached move factory selector. This doesn't scale well, especially for big data problems where in the beginning, just about every moves improves. The neighbourhood size (= amount of selected moves) could for example increase block-wise or timeGradient-wise until an improving solution is found. Notice the difference with the usage of FirstImprovingForager. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBRULES-1457) please support containment test for map keys

by Godmar Back (JIRA)

please support containment test for map keys -------------------------------------------- Key: JBRULES-1457 URL: http://jira.jboss.com/jira/browse/JBRULES-1457 Project: JBoss Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Drl Parser/Builder Affects Versions: 4.0.4 Environment: any Reporter: Godmar Back Using MVEL as the language for clauses, there is no way to test whether a map's key contain a value. For instance: rule "number 1" when e : S(map.keySet() contains "x") then System.out.println("rule number 1"); end leads to a syntax error because Drool's parser does not allow function calls ("keySet())" in clauses. On the other hand, MVEL (according to Mike Brocks, please read http://jira.codehaus.org/browse/MVEL-53 ) does not provide an operator to test containment in a map's set (or values). He said he's considering adding a shortcut such as .keys and .values in 2.0 and recommended I open a Drools JIRA issue. Please provide a way to test for membership in a map's key and value set. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

Create a Java Interface to allow JavaBeans to work more seamlessly as Facts ----------------------------------------------------------------------------- Key: JBRULES-540 URL: http://jira.jboss.com/jira/browse/JBRULES-540 Project: JBoss Rules Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Rule Assemply/SPI Reporter: Mark Proctor Assigned To: Mark Proctor Fix For: 3.1-m1 We want to move management of the bean and its working memory up a layer. When a bean is instantiated by an IoC framework it should weave in an interface to provide better background interoprability between the bean and working memories. further the IoC container should control the life cycle, assert and retract, of that bean in various working memories. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBRULES-1430) Improve Function feature

by longDuck dong (JIRA)

Improve Function feature ------------------------ Key: JBRULES-1430 URL: http://jira.jboss.com/jira/browse/JBRULES-1430 Project: JBoss Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Components: All Affects Versions: 4.0.4 Environment: all Reporter: longDuck dong Priority: Minor The current design of the Function is a bit limiting. for example, if I want to write a function to insert, update or retract facts, the current design does not support it. According to the docs http://downloads.jboss.com/drools/docs/4.0.4.17825.GA/html/ch06s04.html, functions are just helper methods. It would be more powerful if the function always passes the workingmemory to the function. This way, the functions can easily access the globals or access the rule engine. Basically, something similar to JESS funcall http://herzberg.ca.sandia.gov/docs/70/api/jess/Funcall.html. It also makes it easier for developers to encapsulate common actions in the consequence in a function and use it easily from a DSL. The pattern is well proven in CLIPS, JESS and haley. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBRULES-1322) Accumulate functions are highly unreliable for long's and BigDecimals

by Geoffrey De Smet (JIRA)

Accumulate functions are highly unreliable for long's and BigDecimals --------------------------------------------------------------------- Key: JBRULES-1322 URL: http://jira.jboss.com/jira/browse/JBRULES-1322 Project: JBoss Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: Drl Parser/Builder Affects Versions: 4.0.3 Reporter: Geoffrey De Smet Assigned To: Edson Tirelli Priority: Critical Fix For: 4.1.0 When dealing with financial data, one should never ever use double's. Instead BigDecimal should be used. Not because BigDecimal is bigger (that's rarely a problem) but because it doesn't do any decimal to binary transformation. For example, it's impossible for a double to correctly represent "0.2", aka 1/5. Summing many doubles (or even a few differing in scale), can easily give wrong results (and for financial data this tends to be important). Using doubles to sum longs have the exact same problem. Attached is a testcase patch which proves this by checking if (MAX_LONG - 4L) and 3L sum up to be (MAX_LONG - 1L). Currently they don't. One possible way to solve this is to fix JBRULES-1075, which just happens to give drools-solver 3% more performance ;) what a coincidence ^^ -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
