Edge cases

Edge cases

An edge case refers to a scenario that is on the boundary between success and failure, often used to test a known limitation of a system. It is a situation that is not typical or common, but rather an extreme or unusual case that may challenge the system's performance or functionality. Edge cases are often used to identify and address potential weaknesses or vulnerabilities in a system, and to improve its overall robustness.From: A taxonomy of validation strategies to ensure the safe operation of highly automated vehicles [2021], Handbook of Human Factors for Automated, Connected, and Intelligent Vehicles [2020]

dimensional case decays in this time to a much greater degree, the converging wave plays here a much more signihcant role (when rectangular spherical mirrors are employed, this factor is counteracted by the fact that the converging wave propagating from different sections of the edge passes different distances to the axis and, hence, reaches it with different phases, thus bringing about the so-called interference 'quenching'). As was shown (Vinokurov et al 1973, Lyubimov and Orlova 1976) by Weinstein's method, in order to remove degeneracy in circular spherical mirror resonators, the amplitude of the converging wave should be reduced by about eln(27rA^eq)/ln M times compared with the sharp-edge case.

A system level approach of finding critical scenarios based on a robustness metric is presented by Tuncali et al. (2018, 2016). In Tuncali et al. (2018) they use a robustness metric as fitness function for their search algorithm, that follows a combinatorial generation of scenarios, as described in Section 3.3. Aiming to minimize the robustness value, they anticipate to find scenarios that are on the boundary between success and failure, so called boundary or edge cases. Examples for such scenarios are critical just-miss scenarios of other traffic participants or low-speed collisions.
