Optimization is a general term for extremum searching (maximizing or minimizing) of particular properties.
Optimization is also termed Operations research when applied to practical economic problems.
In computer science, optimization is the process of improving a system in certain ways such as execution speed, memory requirements and bandwidth.

 Optimization - Wikipedia, the free encyclopedia
In mathematics, optimization is the discipline which is concerned with finding the maxima and minima of functions, possibly subject to constraints.
An example of an optimization problem is the following: maximize the profit of a manufacturing operation while ensuring that none of the resources exceed certain limits and also satisfying as much of the demand faced as possible.
In computer science, optimization is the process of improving a system in certain ways to reduce the effective runtime, the bandwidth or memory requirements.

 Optimization (computer science) - Wikipedia, the free encyclopedia
In operations research, optimization is the problem of determining the inputs of a function that minimize or maximize its value.
Optimization requires finding a bottleneck: the critical part of the code that is the primary consumer of the needed resource.
Because of this, optimization or performance tuning is often performed at the end of the development stage.

 OPTIMIZATION   (Site not responding. Last check: 2007-10-22)
The term optimization does not apply, usually, when the number of solutions permits the best to be chosen by inspection, using an appropriate criterion (see DECISION THEORY).
The OPTIMAL SOLUTION (or "solution to the optimization problem") is values of decision variables xl, x2,...xn that satisfy the constraints and for which the objective function attains a maximum (or a minimum, in a minimization problem).
Dynamic optimization problems are sometimes referred to as "optimal control problems." There exist special techniques to solve such problems; they often make use of DISCRETIZATION of the independent variables, for example dividing the time axis into a number of intervals and considering the solutions to be constant over those intervals.

 IMA Thematic Year on Optimization, September 2002 - June 2003
Recently several new optimization paradigms and approaches have been proposed which not only have generated a large body of extremely important algorithmic research but have also given birth to new and widely diverse areas to which mathematical optimization is now being and can be applied.
In the case of SDP, this has created interest in the optimization community in such areas as robust optimization (optimization when the problem data is subject to certain types of uncertainty), eigenvalue optimization, robust control and stochastic control.
The general objective is to optimize the parameters expressing the observed data by means of a particular model, and in so doing optimize the microeconomic business objectives of the enterprise.

 Linear Optimization
Optimization models are used extensively in almost all areas of decision-making, such as engineering design and financial portfolio selection.
Optimization problems are often classified as linear or nonlinear, depending on whether the relationship in the problem is linear with respect to the variables.
Optimization problems are classified according to the mathematical characteristics of the objective function, the constraints, and the controllable decision variables.

 Calculus I (Math 2413) - Applications of Derivatives - Optimization   (Site not responding. Last check: 2007-10-22)
In this section we are going to look at another type of optimization problem.  Here we will be looking for the largest of smallest values of a function subject to some kind of constraint.  It’s usually easiest to see how these work with some examples.
Example 1  We need to enclose a field with a fence.  We have 500 feet of fencing material and a building is on one side of the field and so won’t need any fencing.  Determine the dimensions of the field that will enclose the largest area.
In all of these problems we will have two functions.  The first is the function that we are actually trying to optimize and the second will be some constraint.  The constraint will be an equation that must be true no matter what else is happening in the problem.
