The Exclusion of Regions Method (TERM) and Concurrent Gradients Method (CGM) for multi-objective optimization of objective functions considered in a multi-dimensional domain are provided. TERM decomposes the domain into a set of non-intersecting sub-regions, and applies a special criterion to each sub-region to determine if it does not contain Pareto-points.

The area is determined in a simple way based on gradients for each objective function calculated on current point. This introduces new a type of numerical analysis in the multi-objective optimization theory, and allows developing extremely efficient optimization algorithms without using the scalarization technique or any kind of heuristic.
