Approximating the maximum size of a k-regular induced subgraph by an upper bound on the co-k-plex number

Let α_{k} and α_{k} denote respectively the maximum cardinality k-regular induced subgraph and the co-k-plex number of a given graph. In this paper a convex quadratic programming upper bound on α_{k} which is also an upper bound on α_{k} will be introduced. The new bound, denoted by υ_{k}, improves...
