Gilles Sadowski c6094cf9e0 MATH-1635: Unit test demonstrating the reported issue.
Test is set to "@Ignore" since the behaviour may be a known limitation.

Gilles Sadowski 226c1fc638 MATH-1636: Remove "isSupportedConnected" (as per STATISTICS-48). 2021-12-01 02:06:16 +01:00
Gilles Sadowski 21e230ae83 MATH-1630: Runtime switch between JDK and CM implementations of the methods defined in "java.lang.Math".
Default is to use the CM implementations in order to retain previous behaviour.
When using the JDK implementations, some unit tests fail (on Java 8).

Class "AccurateMath" was moved to "o.a.c.math4.core" package.
[Unit tests for that class were not moved because they depend on "legacy" classes.]

Gilles Sadowski b222580737 Replace algorithm used in "best list" search.
Although efficient in terms of evaluations, "NelderMeadTransform" fails for
some higher-dimensional test functions.

Gilles Sadowski 6f33d5f0a7 Fix incorrect usage of "ROSENBROCK" test function (unit tests). 2021-08-27 18:35:47 +02:00
Gilles Sadowski cc5ae51f98 Favouring the "expanded" simplex over the "reflected" one.
This modification decreases the number of function evaluations in several
test cases. Note however that the original description of the algorithm
uses the strict inequality...

Gilles Sadowski f58da4abf5 Use default SA setup in "SimplexOptimizerTest" (unit test).
A single additional search finds the optimum of the test functions.

Gilles Sadowski 06ec7ad0bc MATH-1622: Simulated annealing entails at least one additional search.
Also ensure that the "best list" contains at least two points.

Gilles Sadowski 2ccdf8d002 MATH-1622: Simulated annealing variant of "NelderMeadTransform". 2021-08-25 01:50:28 +02:00
Gilles Sadowski 80a7eb1832 Change how simulated annealing affects the transformed simplex (cf. MATH-1622).
Compared with commit 97462b1a1b, this commit is
more consistent with assumptions of the original (non-hybridized) algorithm.

Gilles Sadowski 1e7bce134f Adapt input files for "SimplexOptimizerTest" (unit tests).
The current tests are "baseline" (2D) cases.
Further work should check degradation with increased dimensionality.

Gilles Sadowski 14ebd93426 Relax expected number of evaluations (unit test).
Optimization is sensitive to the change from "AccurateMath" to "Math"
for computing the "pow" function used in "TestFunction.SUM_POW".

Alex Herbert bdb4160b00 Add variance tests for zero weights
Update javadoc for the behaviour when input weights are zero.

This issue was found when checking the sonar report for the variance
class which has a potential divide by zero if the weights sum to zero.

Alex Herbert 5245a685a0 sonar fix: Handle variance=0 in skewness computation for input array 2021-08-21 14:37:13 +02:00
Alex Herbert 30aa597f1e sonar fix: Ensure checkFeasableCount is not negative.
Change loop condition to 'i <= checkFeasableCount' from 'i <
checkFeasableCount + 1'

This ensures the loop to identify a new feasible column (RealMatrix
arxk) always executes at least once even with checkFeasibleCount at the
limit of 0 or Integer.MAX_VALUE.
