Hello. When building ojalgo in trixie, the build often fails
for different reasons, and I get a failure rate around 13%,
which IMO is not good enough for a stable release.

I've put a small collection of build logs here:

https://people.debian.org/~sanvila/build-logs/ojalgo/

and I'm requesting help to categorize the build failures.

Ideally, for each failing test, we would like to know
if the failure may still happen in unstable or not,
and if the test was disabled or fixed, determine
how it was disabled or fixed.

My ultimate goal would be to have an ojalgo package
in trixie which does not fail to build so easily.

Thanks.

Ok, I've used this simple script to extract the failures:

#!/usr/bin/awk -f
/\[INFO\]/ { status = 2 }
status == 1
/\[ERROR\] Failures:/ { status = 1 }

and the result is attached.

In "histogram" form:

   8 RandomNumberTest.testSampledMean:418
   4 TensorTest.testDeterminantAndTrace:172
   3 SimpleLeastSquaresCase>BasicMatrixTest.testDotAccess1D:270
   3 CaseEigenvalue.testGenerateRandomSomeNegative:271->doTestEigenvaluesOfGenerated:127->doTestEigenvalues:96
   2 TensorTest.testDeterminantAndTrace:171
   2 P20071019Case>BasicMatrixTest.testDotAccess1D:270
   2 P20061119Case>BasicMatrixTest.testDotAccess1D:270
   1 RevisedSimplexSolverTest.testShitingRange:590
   1 RandomNumberTest.testNorm2:371->testDist2:525
   1 PochhammerSymbolTest.testImplementation:78->performTest:57->doTestImplementation:53
   1 PochhammerSymbolTest.testDefinition:70->performTest:62->doTestDefinition:40->compareToGammaImplementation:35
   1 P20050827Case>BasicMatrixTest.testDotAccess1D:270
   1 HypergeometricFunctionTest.testSpecialArguments121:85->lambda$testSpecialArguments121$4:86
   1 CaseEigenvalue.testGenerateRandomAllNegative:261->doTestEigenvaluesOfGenerated:127->doTestEigenvalues:96

Should we just take the four most failing ones and call it a day?
Or should we disable all of them?
How many of those tests are fixed in unstable and how they were fixed?

Thanks.

Ok, three of the failing tests have @Tag("unstable") in version 56.2.1.
Those are ideal candidates to be disabled in trixie as well.

This will allow the failure rate to be reduced from ~12% to ~6%.

Thanks.
