TechnicalBusiness

The action of making the best or most effective use of a situation or resource.

In engineering, optimization is a mathematical process of finding the maximum or minimum of a function, not just 'making things better.'

The story behind the word. From the Latin 'optimus,' meaning 'best.' It entered the English language in the early 19th century, originally in a philosophical context (the belief that this is the best of all possible worlds) before becoming a technical term.

Word relationships

  • refinement: Refinement makes something more elegant; optimization makes it more efficient.
  • maximization: Maximization only looks at increasing one thing; optimization balances multiple factors for the best result.
  • suboptimization: Suboptimization is the practice of optimizing one part of a system at the expense of the whole.

Commonly confused with

  • improvement: Improvement is any positive change; optimization is reaching the 'best' possible state.

Word family

  • optimize (verb): To make as perfect or effective as possible.
  • optimum (noun/adjective): The most favorable condition.

Collocations

  • process optimization
  • cost optimization
  • mathematical optimization
  • search engine optimization

Example sentences

  • "We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil." A famous warning against focusing on the wrong details in programming. (Donald Knuth, Structured Programming with go to Statements)
  • "The software performed a route optimization to ensure drivers spent the least amount of time in traffic." Improving delivery routes for a courier company.

Memory hook

Think of 'Optimus Prime' from Transformers—the 'best' and most 'optimal' leader. Aim for the best.

When not to use

Avoid using it as a synonym for 'improvement' if no specific constraints or goals are being balanced.

Fun facts

  • The term 'optimization' was rarely used in mathematics until the development of linear programming in the 1940s.
