**"NOTIONS OF OPTIMALITY EXTENDED TO MULTICRITERIA OPTIMIZATION MODELS."
**

** Abstract:**
For optimization problems with single-valued objective functions,
little ambiguity is encountered in defining an optimal point as one which
maximizes the given objective. For problems with multiple objectives, or
equivalently for vector-valued objective functions, such notions of optimality
are ill-defined. The definition of an "optimal" solution will vary depending
on the solution model, and in many cases will determine the generating
algorithm. We will contrast various notions of optimality in the context of
their respective algorithms and solution models.
