Kulmavaihtoehto

Kulmavaihtoehto is a Finnish term formed from kulma, meaning angle or corner, and vaihtoehto, meaning option or alternative. In Finnish discourse the phrase is used to describe a problem-solving approach that emphasizes analyzing corner cases or extreme points of a problem space. It appears mainly in educational or theoretical contexts rather than as a formal, standardized method.

In mathematics, computer science and operations research, kulmavaihtoehto can refer to considering the boundary or extreme configurations of a domain to test feasibility, stability, or optimality. The concept is similar to boundary analysis or worst-case scenario testing. The term is typically used informally in Finnish textbooks or lecture notes to illustrate the idea of checking limiting cases.

Etymology and usage notes: kulma means angle or corner, and vaihtoehto means option or alternative. The compound highlights selecting among alternative corner points or extreme cases rather than exploring the entire space.

Examples of use often appear in teaching contexts: in a two-variable optimization problem with constraints, the kulmavaihtoehto would involve evaluating the objective function at the corner points of the feasible region to assess feasibility or performance.
