A Polynomial Algorithm for a Class of 0–1 Fractional Programming Problems Involving Composite Functions, with an Application to Additive Clustering

Abstract: We derive conditions on the functions ', , v and w such that the 0-1 fractional programming problem max w.x/ on OE0I C1/. In particular we show that when ' is convex and increasing, is concave, increasing and strictly positive, v and w are supermodular and either v or w has a monotonicity property, then the 0-1 fractional programming problem can be solved in polynomial time in essentially the same time complexity than to solve the fractional programming problem max, and this even if ' and are nonrational funct… Show more

“…Also [11] develops an FPTAS for a general quasiconcave minimization problem. Note that in contrast, the maximization variant of the ratio problem (2) with S = 2 [n] can be solved in polynomial time via the Dinkelbach algorithm; see [8] and references therein. We first establish the NP-hardness of the maximum expected value all-ornothing subset.…”
