**linear cost function** — Cost behaviour that, when plotted on a graph against activity levels, results in a straight line. For example, total fixed cost levels and variable costs per unit of activity will both result in a straight line horizontal to the x axis when… … Accounting dictionary

**Linear programming** — (LP, or linear optimization) is a mathematical method for determining a way to achieve the best outcome (such as maximum profit or lowest cost) in a given mathematical model for some list of requirements represented as linear relationships.… … Wikipedia

**Linear-quadratic-Gaussian control** — In control theory, the linear quadratic Gaussian (LQG) control problem is one of the most fundamental optimal control problems. It concerns uncertain linear systems disturbed by additive white Gaussian noise, having incomplete state information… … Wikipedia

**Linear-quadratic regulator** — The theory of optimal control is concerned with operating a dynamic system at minimum cost. The case where the system dynamics are described by a set of linear differential equations and the cost is described by a quadratic functional is called… … Wikipedia

**Linear classifier** — In the field of machine learning, the goal of classification is to group items that have similar feature values, into groups. A linear classifier achieves this by making a classification decision based on the value of the linear combination of… … Wikipedia

**semi-fixed cost** — stepped cost An item of expenditure that increases in total as activity rises but in a stepped, rather than a linear, function (see linear cost function). For example, the costs of one supervisor may be required for a particular range of activity … Accounting dictionary

**semi-fixed cost** — stepped cost An item of expenditure that increases in total as activity rises but in a stepped, rather than a linear, function (see linear cost function). For example, the costs of one supervisor may be required for a particular range of activity … Big dictionary of business and management

**step-function cost** — An item of expenditure that when plotted on a graph against activity levels gives a stepped function; i.e. increments of cost are incurred as activity rises. See also: semi fixed cost, linear cost function … Accounting dictionary

**Linear hash** — Linear Hashing is a dynamic hash table algorithm invented by Witold Litwin (1980) [ Citation | first1=Witold | last1=Litwin | title=Linear hashing: A new tool for file and table addressing | journal=Proc. 6th Conference on Very Large Databases |… … Wikipedia

**Linear filter** — A linear filter applies a linear operator to a time varying input signal. Linear filters are very common in electronics and digital signal processing (see the article on electronic filters), but they can also be found in mechanical engineering… … Wikipedia
