The user should select this menu item, when he/she has finished
the specification of a new multi-criteria optimization problem.
Once the Run item from the Pareto_sol. main menu
item is selected the following actions are performed:
The control of the program is turned over to MCMA.
The optimization problem is generated and solved.
The last solution is processed and converted to the ISAAP
data structures.
The control is transferred back to the user, who can either
make a new iteration of MCMA or break the analysis.
The last solution is added to the History records.
The values of criteria for the last solution
are marked by white circles which are connected by a thin line
to the corresponding values of the previous solution
(marked by green circles).
The values of criteria of the previous solution are labeled, if
the previous solution is in the set of solutions that are
displayed (see Section 4.5).
In the current distribution of MCMA the following two solvers are provided:
HOPDM (see [GoM95]), interior point based
LP solver, especially efficient for medium and large scale
problems.
MOMIP (see [OgZ96]), modular optimizer for
Mixed Integer Programming (MIP) problems.
The default selection of the solver is done by MCMA.
HOPDM is chosen for LP optimization problems and
MOMIP for MIP problems.
The set of solver parameters is selected in order to allow for efficient
solving of a broad class of respective types of optimization problems.
The user is advised to contact the authors
should the solution time become unacceptable.
A problem specific tuning of solver parameters may substantially
improve the performance of a solver.
