I wondered about that, but then why is there a lower limit at all? The history shows that the minimum was previously lower, but there are suggestions that the counts may have been inaccurate. At one point the limits were 590 < n < 610 which would definitely not work now! > Regards, > Gilles > > > > > Sebb > > [1] > > https://github.com/apache/commons-math/blob/b0cefc56c67bd41ec9f14311f058d319b05c0312/commons-math-legacy/src/test/java/org/apache/commons/math4/legacy/optim/nonlinear/scalar/MultiStartMultivariateOptimizerTest.java#L75-L76 > > > > - > To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org > For additional commands, e-mail: dev-h...@commons.apache.org > - To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org

[MATH] MultiStartMultivariateOptimizerTest.testCircleFitting flaky test
The test MultiStartMultivariateOptimizerTest.testCircleFitting [1] seems to be flaky. It often fails with values below the expected minimum of 750. Does this indicate a real failure, or can the minimum be safely reduced?
