Abstract The Coffee Berry Borer (CBB) is the main pest that affects coffee crops around world, causing major economic losses and diminishing beverage quality. A mathematical model formulated, from perspective of Adaptive Dynamics (AD) framework, to describe evolution quality as a continuous differentiating attribute related mix healthy bored coffee. study involves three stages: first, an agro-e...

This paper explores the requirements and issues related to media-on-demand electronic commerce using agents as mediators in the customer-to-business and business-to-business relations and propose an architecture for multi-agent systems acting on a wide range of situations. Agent technology is suitable since media-ondemand is a personalised service by nature. The agents' roles are examined in th...

A new active set algorithm (ASA) for large-scale box constrained optimization is introduced. The algorithm consists of a nonmonotone gradient projection step, an unconstrained optimization step, and a set of rules for switching between the two steps. Numerical experiments and comparisons are presented using box constrained problems in the CUTEr and MINPACK test problem libraries. keywords: Nonm...
