Some improvements to the matching algorithm

24 lines of code changed in 1 file:

• Compiler/BackEnd: Matching.mo (+24 -25)

bachmann 2015-04-09 14:33 Rev.: 25472

Added another implementation of the "usual" matching algorithm. Method also
works in combination with the available index reduction methods.

Option: +matchingAlgorithm=BB.

Preliminary tests show similar performance compared with the default matching
algorithm "PFPlusExt" even for large models! Method might be renamed and set
to default, after some small issues in connection with the removeSimpleEquations
modul are solved!

bachmann 2014-11-24 17:56 Rev.: 23545

Added new nonlinear solver based on damped Newton algorithm in combination with homotopy strategy.
Set as default nonlinear solver for running the coverage tests tonight.
Already support of current testsuite, although some details are not implemented completely:
- Proper assert handling
- Use of Modelica homotopy operator
- Improved scaling of homotopy functions
- ...

Improvements will come!!!
