You may solve a system of equations and inequalities
by calling the `ALIAS-Maple` procedures:

GeneralSolve GradientSolve HessianSolveMost of the solving procedures may deal with inequalities constraints but in the list of functions you must first define the equations and then the inequalities. For using these solvers it is needed to create C++ programs that interval evaluate the equations and their derivatives in the appropriate format. By default these procedures will use

The name of the executable created by ALIAS-Maple is `_GS_` but
this may be changed by assigning another string to the variable
``ALIAS/name_executable`` or by setting the string ``ALIAS/ID``.

The calculation done by these procedures may be stopped although the
calculation has not been completed by setting the variable
``ALIAS/time_out`` to a floating point that indicates the maximum
computation time in minutes. In that case the procedure will return a
time out signal together with the solutions that have been obtained up
to now. For example for a problem with 2 variables the message will
be:

[[TIME_OUT],[[1.,1.],[2.,2.]],[[2.5,2.5],[3.,3.]]]which indicates that 2 solutions have been found before the time-out occurs.
