We give a model of parallel distributed genetic improvement. With modern low cost power monitors; high speed Ethernet LAN latency and network jitter have little effect. The model calculates a minimum usable mutation effect based on the analogue to digital converter (ADC)’s resolution and shows the optimal test duration is inversely proportional to smallest impact we wish to detect. Using the ex...

The destruction of quantum coherence can pump energy into a system. For our examples this is paradoxical because the destroyed correlations are ordinarily considered negligible. Mathematically the explanation is straightforward and physically one can identify the degrees of freedom supplying this energy. Nevertheless, the energy input can be calculated without specific reference to those degree...

A central problem in wireless packet networks is the efficient resolution of collisions among nodes with independent transmission schedules. Natural metrics for measuring the efficiency of any collision resolution scheme include total time taken for collision resolution, average participation time of each transmitter during contention resolution, average number of transmissions made by a transm...
