Abstract: A computer-implemented method for updating a modeled object comprises providing an old operand of an operation, a result of applying the operation to the old operand, wherein applying the operation to the old operand includes computing old sub-results, each old sub-result being determined by a respective old sub-operand of the old operand, and a new operand including a first set of sub-operands of the new operand at least partially identical to old sub-operands of the old operand, and a second set of new sub-operands. The method further comprises applying the operation on the new operand, including computing new sub-results determined by a respective sub-operand of the second set; and retrieving the old sub-results determined by the old sub-operands of the old operand to which sub-operands of the first set are at least partially identical. Such a method improves the update of the modeled object.
