If the system exhibits a structure which can be represented by a mathematical equivalent, called a mathematical model, and if the objective can be also so quantified, then some **computational** method may be evolved for choosing the best schedule of actions among alternatives. Such use of mathematical models is termed mathematical programming.

Suppose that the organism is given the problem of determining the analysis of a stimulus at a certain level of representation- e.g., the problem of determining which sequence of words a given utterance encodes. Since, in the general case, transducer outputs underdetermine perceptual analyses, we can think of the solution of such problems as involving processes of nondemonstrative inference. In particular, we can think of each input system as a **computational** mechanism which projects and confirms a certain class of hyputheses on the basis of a certain body of data.

Algorithms are the **computational** content of proofs.

One is forced to assume that ordinary people have the **computational** capabilities and statistical software of econometricians.

Broadly stated, the task is to replace the global rationality of economic man with a kind of rational behavior that is compatible with the access to information and the **computational** capacities that are actually possessed by organisms, including man, in the kinds of environments in which such organisms exist.

[I]t is particularly encouraging to see the growing number of **computational** studies being conducted at the cellular and molecular levels. Perhaps no where else in neuroscience is the risk of getting lost in the trees and separated from overall brain function as great.
