2.5.15. Related to a common problem

Denotes the fact that a constraint C π‘’π‘›π‘‘π‘Ÿπ‘¦ and a constraint C π‘Žπ‘™π‘ π‘œ are related to a same problem (i.e.,Β they can both be used for modelling that problem).

EXAMPLE: As an example, the constraints C π‘’π‘›π‘‘π‘Ÿπ‘¦ = πšŒπš˜πš•πš˜πš›πšŽπš_πš–πšŠπšπš›πš’πš‘ and C π‘Žπ‘™π‘ π‘œ = πšœπšŠπš–πšŽ can both be used for modelling the matrix reconstruction problem.
