Research Type Theoretical We introduce a new framework that allows the objective to be a more general function of the number of errors at each vertex (for example, we may wish to minimize the number of errors at the worst vertex) and provide a rounding algorithm which converts fractional clusterings into discrete clusterings while causing only a constant-factor blowup in the number of errors at each vertex. This rounding algorithm yields constant-factor approximation algorithms for the discrete problem under a wide variety of objective functions. Solving the problem numerically, we obtained the following values for the parameters: α = 0.465744 γ = 0.0887449 k1 = 0.767566 k2 = 0.117219 k3 = 0.308433. These parameters yield an approximation ratio of roughly 48.
