Increased demand for corn for ethanol production has helped push grain prices to record levels. This has increased livestock production costs, and producers have responded with changes to production systems. This paper explores the degree to which costs can be mitigated with alternative feeds, the effect this might have on physical performance, and the impact of alternative feeds on the competi...

In this paper we present an evolutionary approach as an alternative to the search of a solution near to the problem NP-complete of assigning rules to processors This problem appears when parallelism of production is to be applied to Production Systems (PS) or Rule Based Systems. Nowadays we are building a testbed system for the development and the execution of this kind of systems, in which we ...
