Singular Manual: Cooper philosophy

| ### C.8.2 Cooper philosophy #### Computing syndromes in cyclic code case #### CRHT-ideal Replace the concrete values above by variables and add some natural restrictions. Introduce #### General error-locator polynomial For an example see `sysCRHT` in decodegb_lib. More on Cooper's philosophy and the general error-locator polynomial can be found in [OS2005]. #### Finding the minimum distance The method described above can be adapted to find the minimum distance of a code. More concretely, the following holds: For an example see `sysCRHTMindist` in decodegb_lib. More on finding the minimum distance with Groebner bases can be found in [S2007]. See [OS2005], for the definition of the polynomial above.
