Tomlab Optimization's upgrade and support contract, TUSC, entitles you to: access to optimization software experts to solve reported problems; software enhancements, improvements and updates; and new versions of your Tomlab toolboxes as they are released.

TUSC is compulsory for multi-user licenses.

All new licenses, except Tomlab /CPLEX, includes TUSC for 30 days. Thereafter, TUSC is available at a yearly rate of 15% of the current list price, payable in advance. TUSC cover must be continuous from the purchase date, and must be renewed within 30 days of expiry to qualify for this rate. If a license has not been covered continuously by TUSC, and you wish to purchase backdated TUSC to bring TUSC up to date, or TUSC is renewed more than 30 days after expiry, the cost is 25% of the current list price per year, backdated to when TUSC lapsed. If TUSC has lapsed by more than three years, customers may instead trade in their existing license for an 25% discount.
