[jira] [Created] (MATH-586) Allow using a custom root-finding
algorithm to detect state events
Allow using a custom root-finding algorithm to detect state events
------------------------------------------------------------------
Key: MATH-586
URL: https://issues.apache.org/jira/browse/MATH-586
Project: Commons Math
Issue Type: Improvement
Affects Versions: 3.0
Environment: n/a
Reporter: Dennis Hendriks
Fix For: 3.0
When using an ODEIntegrator, event handlers can be added. The event handlers result in the construction of an EventState instance. Internally, that class uses a hard-coded instance of BrentSolver as root-finding algorithm. It should be possible to provide a custom root-finding algorithm to detect state events.
