I'm looking into the CAPA physics problems. The problems are stored in folders named type01, type02, ...
My first question is what are these "types" about? Is this a classification based on different subject matter in physics? Is it a classification based on the code structure of the original LON CAPA problems and the automated conversion that was made to WeBWorK?
If it is a classification based on subject matter, does anyone have a mapping? (Something like "type02 is constant velocity problems, etc".)
Lastly, some type numbers appear to be missing: 07, 11, 14, 23, 28, 31, 34, 44, and 46. The last type folder is 47, but the CAPA_graphics folder indicates that at some point the types went all the way up to at least type 91. Does anyone know the story of the missing types? Were they never successfully converted (except for many their images were captured?)
