Given an instance I of a minimization problem with optimum opt, fixed parameter ρ(k) inapproximability is to find a k ≥ opt and prove that it is not possible to compute a solution of value ρ(k) · k usually under the eth. In this paper we are interested only in k being the optimum value of some instance. Our question is: What properties make a good Fixed Parameter Inapproximability proof? We cla...

Given an instance I of a minimization problem with optimum opt, fixed parameter ρ(k) inapproximability is to find a k ≥ opt and prove that it is not possible to compute a solution of value ρ(k) · k. In this paper all proofs are under the eth, and we are interested only in k being the optimum value of some instance. Our question is: What properties make a good Fixed Parameter Inapproximability p...

In Bangladesh, potato (Solanum tuberosum L.) lacks optimum quality for export or processing industries. Optimum utilization of specific plant nutrients can improve quality. The experiment was conducted to evaluate the best dose(s) phosphorus in combination with potassium sources as they affect tuber consisted factors: dose(4); P1 = 200 kg ha-1 TSP @ 42.55 P; P2 220 46.81 P, P3 240 51.06 P and P...
