  2. Evaluation strategy - Wikipedia

    en.wikipedia.org/wiki/Evaluation_strategy

    A non-strict evaluation order is an evaluation order that is not strict, that is, a function may return a result before all of its arguments are fully evaluated. [28]: 46–47 The prototypical example is normal order evaluation, which does not evaluate any of the arguments until they are needed in the body of the function. [29]

  3. Dependency graph - Wikipedia

    en.wikipedia.org/wiki/Dependency_graph

    A correct evaluation order is a numbering : of the objects that form the nodes of the dependency graph so that the following equation holds: () < (,) with ,. This means, if the numbering orders two elements a {\displaystyle a} and b {\displaystyle b} so that a {\displaystyle a} will be evaluated before b {\displaystyle b} , then a ...

  4. Lazy evaluation - Wikipedia

    en.wikipedia.org/wiki/Lazy_evaluation

    Lazy evaluation is difficult to combine with imperative features such as exception handling and input/output, because the order of operations becomes indeterminate. The opposite of lazy evaluation is eager evaluation, sometimes known as strict evaluation. Eager evaluation is the evaluation strategy employed in most [quantify] programming languages.

  5. Order of operations - Wikipedia

    en.wikipedia.org/wiki/Order_of_operations

    Order of operations. In mathematics and computer programming, the order of operations is a collection of rules that reflect conventions about which operations to perform first in order to evaluate a given mathematical expression. These rules are formalized with a ranking of the operations.

  6. Lambda calculus - Wikipedia

    en.wikipedia.org/wiki/Lambda_calculus

    On the other hand, typed lambda calculi allow more things to be proven. For example, in simply typed lambda calculus, it is a theorem that every evaluation strategy terminates for every simply typed lambda-term, whereas evaluation of untyped lambda-terms need not terminate (see below). One reason there are many different typed lambda calculi ...

  7. Evaluation - Wikipedia

    en.wikipedia.org/wiki/Evaluation

    In common usage, evaluation is a systematic determination and assessment of a subject's merit, worth and significance, using criteria governed by a set of standards.It can assist an organization, program, design, project or any other intervention or initiative to assess any aim, realizable concept/proposal, or any alternative, to help in decision-making; or to generate the degree of ...

  8. PRECEDE–PROCEED model - Wikipedia

    en.wikipedia.org/wiki/Precede–proceed_model

    The PRECEDE–PROCEED model is a cost–benefit evaluation framework proposed in 1974 by Lawrence W. Green that can help health program planners, policy makers and other evaluators, analyze situations and design health programs efficiently. [1]

  9. Program evaluation - Wikipedia

    en.wikipedia.org/wiki/Program_evaluation

    Program evaluation is a systematic method for collecting, analyzing, and using information to answer questions about projects, policies and programs, [1] particularly about their effectiveness and efficiency.
