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

e052d9dc53 Remove methods that were calling the "Math" implementation. 2021-10-17 02:03:42 +02:00
Gilles Sadowski
22753536f4 Class "JdkMath" bridges user code and alternative implementations. 
It's a "drop-in" replacement for JDK's "Math" as of Java 8 (cf. MATH-1630).

"AccurateMath" contains pure Java, acccurate, implementations of "Math" functions.
But it is no longer required to implement all of them.

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.]

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...

80a7eb1832 Change how simulated annealing affects the transformed simplex (cf. MATH-1622). 
Compared with commit 97462b1a1b6f64ab10e06db331d5b6762d979aab, this commit is
more consistent with assumptions of the original (non-hybridized) algorithm.
