Edikan E. Akpanibah and Bright O. Osu, Portfolio Strategy for an Investor with Stochastic Premium Under Exponential Utility via Legendre Transform and Dual Theory, Volume 2017, Number 6, Pages 27-35, 2017

Abstract: We investigate the optimal investment strategies of an insurance company. We assume that the rates at which premiums are paid to insurance companies are stochastic, the total claims are modeled by a compound Poisson process, we assume that surplus of the insurance company is invested...

Abstract: It is known that a homeomorphism between two topological spaces preserves all the topological properties such as connectedness and compactness. To a map of spaces we can associate a homomorphism of groups such that compositions of maps yield compositions of homomorphisms of groups. Then any...

Bochar Laarabi and Bouchaib Radi, A Two-Phase Heuristic Method for Solving Team Orienteering Problem, Volume 2017, Number 6, Pages 10-19, 2017

Abstract: The Team Orienteering Problem $(TOP)$ is an catchy variant of the Vehicle Routing Problem $(VRP)$. The aim at maximizing the total amount of profit collected by a fleet of vehicles while not exceeding a predefined travel cost limit on each vehicle. In this paper,we propose...

Surendra Kumar Tiwari and Kaushik Das, Cone Metric Spaces and Fixed Point Theorems for Generalized T-Reich Contraction with c-Distance, Volume 2017, Number 6, Pages 1-9, 2017

Abstract: A new concept of the c-distance in cone metric spaces has been introduced by Cho et al. [8] in 2011. Recently, Fadail et al. [24] in 2017 introduced the $T$-Reich contraction under the concept of $c$-distance in cone metric spaces and proved uniqueness fixed point...
