public enum AllowedSolution extends Enum<AllowedSolution>
(bracketed univariate real) rootfinding algorithm
may accept as solutions.
This basically controls whether or not underapproximations and
overapproximations are allowed.
If all solutions are accepted (ANY_SIDE
), then the solution
that the rootfinding algorithm returns for a given root may be equal to the
actual root, but it may also be an approximation that is slightly smaller
or slightly larger than the actual root. Rootfinding algorithms generally
only guarantee that the returned solution is within the requested
tolerances. In certain cases however, in particular for
state events
of
ODE solvers
, it
may be necessary to guarantee that a solution is returned that lies on a
specific side the solution.

Enum Constant and Description 

ABOVE_SIDE
Only solutions for which values are greater than or equal to zero are
acceptable as solutions for rootfinding.

ANY_SIDE
There are no additional side restriction on the solutions for
rootfinding.

BELOW_SIDE
Only solutions for which values are less than or equal to zero are
acceptable as solutions for rootfinding.

LEFT_SIDE
Only solutions that are less than or equal to the actual root are
acceptable as solutions for rootfinding.

RIGHT_SIDE
Only solutions that are greater than or equal to the actual root are
acceptable as solutions for rootfinding.
