2.5.3. Attached to cost variant

Constraint ${C}_{\mathrm{𝑎𝑙𝑠𝑜}}$ is the original version attached to the cost variant constraint ${C}_{\mathrm{𝑒𝑛𝑡𝑟𝑦}}$.

EXAMPLE: As an example, constraint ${C}_{\mathrm{𝑎𝑙𝑠𝑜}}=$ $\mathrm{𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝}$ is the original version attached to the cost variant constraint ${C}_{\mathrm{𝑒𝑛𝑡𝑟𝑦}}=$ $\mathrm{𝚖𝚒𝚗𝚒𝚖𝚞𝚖}_\mathrm{𝚠𝚎𝚒𝚐𝚑𝚝}_\mathrm{𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝}$, 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.
