Brent solver shouldn't need strict ordering of min, max and initial
-------------------------------------------------------------------

                 Key: MATH-347
                 URL: https://issues.apache.org/jira/browse/MATH-347
             Project: Commons Math
          Issue Type: Bug
    Affects Versions: 2.0
            Reporter: Volkan Aktas


The "solve(final UnivariateRealFunction f, final double min, final double max, 
final double initial)" function calls verifySequence() which enforces a strict 
ordering of min, max and initial parameters. I can't see why that is necessary 
- the rest of solve() seems to be able to handle "initial == min" and "initial 
== min" cases just fine. In fact, the JavaDoc suggests setting initial to min 
when not known but that is not possible at the moment.
