ON BOUNDEDNESS OF $\epsilon$-APPROXIMATE SOLUTION SET OF CONVEX OPTIMIZATION PROBLEMS

Boundedness for the set of all the $\epsilon$-approximate solutions for convex optimization problems are considered. We give necessary and sufficient conditions for the sets of all the $\epsilon$-approximate solutions of a convex optimization problem involving finitely many convex functions and a convex semidefinite problem involving a linear matrix inequality to be bounded. Furthermore, we give examples illustrating our results for the boundedness.
