[jira] Commented: (MATH-351) SimplexSolver fails to solve feasible problem instance
[ https://issues.apache.org/jira/browse/MATH-351?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12852538#action_12852538 ] Mark Thomas commented on MATH-351: -- I haven't had a chance yet to verify for myself that this works on 2.1, but if it works for you, Luc and you consider the epsilon discussion a separate issue, I'm happy with closing this as invalid (especially if it will lead to an earlier release of 2.1 =). For other readers, it appears that there were bug fixes for Simplex which weren't in 2.0, but have been incorporated into the trunk (see: http://issues.apache.org/jira/browse/MATH-302). If this is so, we'll want to leave this link in. Thanks guys and sorry for the mix up.

[jira] Created: (SCXML-117) A multi-thread supported service and custom action management system for Apache Commons SCXML engine
A multi-thread supported service and custom action management system for Apache Commons SCXML engine Key: SCXML-117 URL: https://issues.apache.org/jira/browse/SCXML-117 Project: Commons SCXML Issue Type: New Feature Environment: Java environment Reporter: Gui Xunlong Abstract: Apache Commons SCXML is an implementation aimed at creating and maintaining a Java SCXML engine capable of executing a state machine defined using a SCXML document which is very useful to handler complex status transfer logic.This project aims to implement a multi-thread supported service and custom action management system for Commons SCXML. Description: State Chart XML (SCXML) provides a generic state-machine based execution environment based on Harel State Tables and is very useful to handler complex status transfer logic.Apache Commons SCXML is an implementation aimed at creating and maintaining a Java SCXML engine capable of executing a state machine defined using a SCXML document. It is just a single thread SCXML engine,if user want to implement a whole SCXML based application, he must do some secondary development jobs. This project aims to develop a open source multi-thread SCXML services management system. It includes these main function module,and this is also what i need to do: 1.Custom actions management module All the system custom actions are registered in a configuration xml named system_custom_actions.xml. Each custom action Java Class must implement interface org.apache.commons.scxml.model.Action, and write practical code in function execute(final EventDispatcher evtDispatcher, final ErrorReporter errRep, final SCInstance scInstance, final Log appLog, final Collection derivedEvents) When system initializate, load all the custom actions Class from system_custom_actions.xml,instance them and add them into system context environment.User can use this mechanism to add his own custom actions to the system Create a Java Swing based Graphics User Interface to add,modify,delete custom actions into the system. 2.Thread pool management module Use a thread pool mechanism to manage SCXML engines. The thread pool properties information is stored in a XML confiuration file named system_thread_pool.xml,it includes these attributes: min_thead_number,max_thread_number,thread_release_timespan may be some more When system initializate, it will instance several SCXML engines objects according to min_thread_number. If these thread are all busy, but one new service is start,system will start a new thread to handle this service. The thead number can not outstrip max_thread_number. If a thread has been free for a period of time which is marked by attribute thread_release_timespan,system will release this thread. 3.Service management module Every application service is a SCXML document,all the system services are registered in a configuration xml file named system_service.xml, each service has a unique id which is used to mark the service. 4.Service manage and monitor module Build a Java Swing GUI to check service list,start,stop,deploy or delete some services.And also, it has a sub system to monitor running service status,look over data in running context,reset this service or kill it. 5.Event dispatch module Implement a EventDispather class instance to send Event to the system. Each Event will contain a service id which is used to mark its owner service and specific event content. This is a whole SCXML deploy and management system. If user want to implement some SCXML based application, just write proper SCXML document and corresponding custom actions,register them in to the system,and start the service,it is done. I think it is a practical SCXML engine,it will make Apache Commons SCXML more and more popular,In fact, i have finish some function module, such as custom action management module. I think this is a proper project for GSoC under Apache Commons SCXML, but i have not a mentor yet, any one interested in it, please contact ustbco...@gmail.com -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.

[jira] Updated: (MATH-351) SimplexSolver fails to solve feasible problem instance

I am using the trunk version of the code. I also found that 2.0 contained some errors. In the new versions I have not found anything strange. Interesting to me is the use of epsilon. I have found that the default value of 1e-6 works fine for most problems. However, consider the following problem: The answer to this problem is trivial to find; i.e. and . However, for the case when we get a wrong answer; i.e. for we find that and (the second constraint is not satisfied), and even for no feasible solution could be found. Too me the results of this very simple problem are obvious. But how do you determine the threshold for epsilon for general problems? Do you analyze the condition number of the constraints matrix?
