2.5.3. Attached to cost variant

Constraint C 𝑎𝑙𝑠𝑜 is the original version attached to the cost variant constraint C 𝑒𝑛𝑡𝑟𝑦 .

EXAMPLE: As an example, constraint C 𝑎𝑙𝑠𝑜 = 𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝 is the original version attached to the cost variant constraint C 𝑒𝑛𝑡𝑟𝑦 = 𝚖𝚒𝚗𝚒𝚖𝚞𝚖_𝚠𝚎𝚒𝚐𝚑𝚝_𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝, where the total cost of a solution is the sum of the costs associated with the fact that we assign a given value to a specific variable.
