Stefan Müller f66e3fc2d8 Removed full data test cases
Providing full access to the solver code is the purpose of this project
repository. However, I think there should be some work in getting to
the actual solutions to not open the doors to abuse.

Stefan Müller 7db8f948c5 Changed TPolynomialRoots.BisectIsolation return type to array 2024-05-26 17:34:18 +02:00
Stefan Müller 8d4a5c2ed8 Changed root finder to use base-2 exponent of bound
Since the root isolation algorithm uses a power of two as bound anyway,
it makes sense to use it's exponent in method interfaces and throughout
the algorithm. This simplifies multiplications to cheap shifts and will
make it easier to detect when the isolating interval size is 1.

Also added some method documentation.
