Minimum covering polyplet
A minimum covering polyplet (MCP) of a pattern is a polyplet (i.e. orthogonally/diagonally connected pattern) of minimal population covering said pattern.[1] The minimum covering polyplet size (MCPS) of a pattern is the size of a minimum covering polyplet[1]; unlike the minimum covering polyplet itself, this is a single, well-defined number.
Computation
Finding a minimum covering polyplet for a given pattern is an instance of the Steiner tree problem,[1] which is NP-hard; however, finding a minimum covering polyplet for a given small pattern is often easy in practice.
Uses
Oscar Cunningham proposed using the minimum covering polyplet size to gauge the size of a methuselah, as it penalizes both population and bounding box.[2] The resulting metric is L/MCPS.

gollark: WASM currently requires JS glue code to interact with DOM APIs, although maybe they'll make some standard for that and implement it directly.

gollark: For example, imagine an HTML sanitization library for blogs or something which parses HTML differently to browsers.
