Gilles Sadowski 9be74e3abd Nit: Display debug file name. 2021-08-16 02:03:08 +02:00
Gilles Sadowski 1d1fe2acc0 Make debugging parameters optional (unit test). 
First optional parameter is the prefix of the output file's name.
Second optional parameter is the list of simplex vertices to save.

Gilles Sadowski 40984b8275 Use JUnit 5 engine (unit tests). 
Unmodified classes rely on JUnit 5 compatibility layer with JUnit 4.

Note: Upgrading to "maven-surefire-plugin" to version 3.0.0-M5 was
necessary since prior to 3.0.0-M4 support for "rerunFailingTestsCount"
was dropped on JUnit 5.

 2021-08-07 13:39:12 +01:00
Gilles Sadowski 50ca244b38 MATH-1622: Hybridation of simplex-based search with simulated annealing (SA). 
Class "SimulatedAnnealing" provides user-defined input ("OptimizationData").
Behaviour of "SimplexOptimizer" depends on whether SA is activated (if yes,
each "iteration" is further split in "epoch" stages).
The "Simplex.TransformFactory" interface is changed to allow passing the SA
acceptance test ("Metropolis" rule).

The "SimplexOptimizer" is furter refactored (cf. MATH-1614) so that the
steps (in method "doOptimize") clearly stand out as
 1. Setup and iteration (optionally with simulated annealing).
 2. Simplex transformation rule.
 3. Convergence check.
 4. "Best list" search.

This commit also contains the following modifications:
 * "TestFunction": Override "toString" (for display in unit tests).
 * "Simplex"
   - Self-documenting names for factories.
   - Utility methods: "centroid", "asList", "replaceLast".
   - Unit tests.
 * "MultiDirectionalTransform":
   - Use common utility methods.
   - Fix missing sort in "transform" method.
   - Check validity of constructor parameters.
   - Parameter names to match the equivalent in "NelderMeadMeadTransform".
 * Adapt unit test classes to the updated API of class "Simplex".
 * "PointValuePair":
   - "final".
   - Implements "hashCode".
