This paper deals with resource unconstrained project scheduling problems with the objective of maximizing the net present value (NPV) of project cash flows. Here we present a heuristic algorithm named as differential procedure (Dif_AOA).&#10In order to evaluate the efficiency of this algorithm, networks with node numbers between 10-1000 and network complexity coefficients between 1.3-6.6 have ...

We provide the first two-party protocol allowing Alice and Bob to evaluate privately even against active adversaries any completely positive, tracepreserving map F ∈ L(Ain ⊗ Bin) → L(Aout ⊗ Bout), given as a quantum circuit, upon their joint quantum input state ρin ∈ D(Ain ⊗ Bin). Our protocol leaks no more to any active adversary than an ideal functionality for F provided Alice and Bob have th...

this study highlights the costs and benefits of indigenous beef cattle fattening schemes in shinyanga urban and kishapu districts in tanzania. specifically, in this study the net profit (np) for fatteners between beef cattle fattening schemes has been determined. the schemes were divided into two main categories, scheme 1 in which the animals were fed on cottonseed hulls (cshl) based diets and ...

in this paper, a novel mathematical model for a preemption multi-mode multi-objective resource-constrained project scheduling problem with distinct due dates and positive and negative cash flows is presented. although optimization of bi-objective problems with due dates is an essential feature of real projects, little effort has been made in studying the p-mmrcpsp while due dates are included i...
