<action dev="tn" type="fix" issue="MATH-1082">
The cutOff mechanism of the "SimplexSolver" in package o.a.c.math3.optim.linear
could lead to invalid solutions. The mechanism has been improved in a way that
the tableau does not need to be updated anymore. Additionally, a new check will
prevent impossible solutions to be returned as valid.
