## Quantitative stability of variational systems. III: $$\varepsilon$$- approximate solutions.(English)Zbl 0802.49009

Starting from the usual problem of solving numerically convex optimization problems the authors analyse data dependence of the algorithms. Continuity with respect to suitable distance between objective functions and sets is considered.
