Notation used throughout the text.
| symbol | meaning |
|---|---|
| x | vector of decision variables |
| Fj(x) | jth indicator function, j = 1 … n |
| F(x) | vector of all n indicator functions |
| Cx | constraint set for the decision variables |
| CF | convexified set of feasible indicator function vectors |
| v, y, z | used to denote points in indicator function space, |
| vi, i = 1 … m | m points in indicator function space representing the Pareto surface |
| CH(v1, v2, … , vm) | convex hull of the m representing points. Serves as approximation of CF |
| d(z → y) | distance (one sided maximum norm) from z to y |
| d(z → S) | distance from z to the set S |
