Abstract: Described are methods, systems, and processor program products for determining a set of costs of routes in a network, including providing a model of the network, optimizing the model for maximum network lifetime, updating the model using at least one constraint based on the maximum network lifetime, optimizing the updated model for minimum network latency, modifying the updated model using a constraint based on the minimum network latency, and, optimizing the modified updated model by balancing the network across multiple pathways to provide costs of routes in the network.

Abstract: An apparatus which permits the index and middle finger of the hand to be spread apart in a manner to stress the finger joints. The joint may then be exercised while in its stressed condition so that the joint is strengthened at the same time as it is made more flexible. The object of the invention is to improve the flexibility and stretch of the finger muscles of the index and middle finger of the hand so that a person utilizing the exerciser may practice the split finger baseball pitch.
