In biology, optimality models are a tool used to evaluate the costs and benefits of different organismal features, traits, and characteristics, including behavior, in the natural world. This evaluation allows researchers to make predictions about an organisms's optimal behavior or other aspects of its phenotype. … See more To construct an optimality model, the behavior must first be clearly defined. Then, descriptions of how the costs and benefits vary with the way the behavior is performed must be obtained. Examples of benefits and costs … See more Cellular sensing Cells exhibit precise behaviors in response to physical cues. This optimality has been modeled by … See more Some authors have argued that optimality models may be insufficient in explaining an organism's behaviour. The degree of optimization in response to natural selection depends on the rate at which genetic structure changes, the amount of additive variance … See more WebThe optimality of a design depends on the statistical model and is assessed with respect to a statistical criterion, which is related to the variance-matrix of the estimator.

WebIn linguistics, Optimality Theory (frequently abbreviated OT) is a linguistic model proposing that the observed forms of language arise from the optimal satisfaction of conflicting constraints. OT differs from other approaches to phonological analysis, which typically use rules rather than constraints. WebYou can use optimality metrics to compare designs, but remember that the optimality of a given D-optimal design is model dependent. That is, optimality is defined for a fixed design size and for a particular model. For instance, when comparing designs, larger D-optimality are better, but smaller A-optimality values better.
