EAGER EVALUATION

Eager evaluation is the evaluation model in most traditional programming languages.

In eager evaluation an expression is evaluated as soon as it gets bound to a variable. This is generally more efficient as a low-level strategy in simple programming languages, as it removes the need to build and manage intermediate data structures representing unevaluated expressions.

However, in more sophisticated programming languages, the low-level optimisation of forced eager evaluation is found to be disadvantageous over lazy evaluation. This is because it prevents the higher-level optimisations and greater expressiveness that can be obtained under the latter method, which generally allows the implementation of both lazy and eager semantics.

Specialty Definition: EAGER EVALUATION

Domain	Definition
Computing	Eager evaluation Any evaluation strategy where evaluation of some or all function arguments is started before their value is required. A typical example is call-by-value, where all arguments are passed evaluated. The opposite of eager evaluation is call-by-need where evaluation of an argument is only started when it is required. The term "speculative evaluation" is very close in meaning to eager evaluation but is applied mostly to parallel architectures whereas eager evaluation is used of both sequential and parallel evaluators. Eager evaluation does not specify exactly when argument evaluation takes place - it might be done fully speculatively (all redexes in the program reduced in parallel) or may be done by the caller just before the function is entered. The term "eager evaluation" was invented by Carl Hewitt and Henry Baker and used in their paper ["The Incremental Garbage Collection of Processes", Sigplan Notices, Aug 1977. (ftp://ftp.netcom.com/pub/hb/hbaker/Futures.html)]. It was named after their "eager beaver" evaluator. See also conservative evaluation, lenient evaluation, strict evaluation. (1994-12-22).
