Fairly substantial change: Factor now Testable, MutableLinearFactor gone

2009-10-13 20:55:07 +00:00
66dac8a52f
Generalized constraint handling to create a LinearConstraint which implements linear equality constraints that can be eliminated as a part of a ConstrainedLinearFactorGraph. DeltaFunction has been changed to be a ConstrainedConditionalGaussian, which has a more robust solve() function. The new tests no longer use the "constrained" example from smallExample, so those functions have been commented.
...
''Limitations: ''
* Any given node can only have one constraint on it, but constraints can be of arbitrary size
* Constraints can only be specified as a blockwise system, where each block must be square and invertible to support arbitrary elimination orderings.
* ConstrainedNonlinearFactorGraph is disabled until a better solution for handling constraints in the nonlinear case is determined.
2009-10-08 13:57:22 +00:00

Removed ConstrainedChordalBayesNet and associated test. It may return if ConstrainedConditionalGaussians need more involved processing in future versions, but for all versions of LinearConstraint, there is no need for a special Constrained CBN.

'''BIG CHANGE''': avoid converting back and to FGConfigs by templating on configuration type. Details:
...
* Factors are now templated on the configuration type. Factor Graphs are now templated on the factor type and configuration type.
* LinearFactor is a factor on an FGConfig.
* LinearFactorGraph uses LinearFactor and FGConfig.
* NonLinearFactor is still templated on Config.
* NonLinearFactorGraph uses NonLinearFactors, but is still templated on Config.
* Tests and VSLAMFactor have been updated to reflect those changes.

2 BIG changes:
...
(1) FactorGraph and NonlinearOptimizer now no longer have a .cpp file, but a -inl.h file as in [http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml Google's C++ Style Guide]. This means if you expect to instantiate one of the functions in a cpp file, you have to include the -inl.h file.
(1) getOrdering is now in FactorGraph, and the non-linear version does *not* take a config anymore.
Long version: I made this change because colamd works on the graph structure alone, and should not depend on the type of graph. Instead, because getOrdering happened to implemented in LinearFactorGraph first, the non-linear version converted to a linear factor graph (at the cost of an unnecessary linearization), and then threw all that away to call colamd. To implement this in a key-neutral way (a hidden agenda), i had to modify the keys_ type to a list, so a lot of changes resulted from that.
