In natural evolution and artificial evolution (e.g. artificial life and evolutionary computation) the fitness (or performance or objective measure) of a schema is rescaled to give its effective fitness which takes into account crossover and mutation. Effective fitness is used in Evolutionary Computation to understand p...

designing fitness functions with algorithms like novelty search in which the objective of the agents is unknown. In the case of bacteria effective fitness could include production of toxins and rate of mutation of different plasmids, which are mostly stochastically determined == Applications == When evolutionary equati...

The desert fungi are a variety of terricolous fungi inhabiting the biological soil crust of arid regions. Those exposed to the sun typically contain melanin and are resistant to high temperatures, dryness and low nutrition. Species that are common elsewhere (e.g. Penicillium spp. and common soil Aspergillus spp.) do no...

In physics, a conservation law states that a particular measurable property of an isolated physical system does not change as the system evolves over time. Exact conservation laws include conservation of mass-energy, conservation of linear momentum, conservation of angular momentum, and conservation of electric charge....

inversion or reversal of space, time, and charge. Conservation laws are considered to be fundamental laws of nature, with broad application in physics, as well as in other fields such as chemistry, biology, geology, and engineering. Most conservation laws are exact, or absolute, in the sense that they apply to all poss...

Local conservation also implies global conservation; that the total amount of the conserved quantity in the Universe rem...

The more general inhomogeneous case: y t + A ( y ) y x = s {\displaystyle y_{t}+A(y)y_{x}=s} is not a conservation equation but the general kind of balance equation describing a dissipative system. The dependent variable y is called a nonconserved quantity, and the inhomogeneous term s(y,...
