The minimax principle

WebAug 23, 2024 · The minimax criterion is the choice from a set of options that minimizes the risk of a worse-case scenario. This is often not an optimal choice as minimization of a risk can be extremely expensive and result in missed opportunities. Also, by focusing on the worse-case, less severe risks may be neglected even if they are far more likely to occur. WebIn mathematics, the Courant minimax principlegives the eigenvaluesof a real symmetric matrix. It is named after Richard Courant. Introduction[edit] The Courant minimax principle gives a condition for finding the eigenvalues for a real symmetric matrix. For any real symmetric matrix A,
