Abstract: This paper presents some examples of ill-behaved central paths in convex optimization. Some contain infinitely many fixed length central segments; others manifest oscillations with infinite variation. These central paths can be encountered even for infinitely differentiable data.

Keywords: central path --convex optimization --interior point algorithm --nonlinear programming --penalty function methods
