Abstract
A method of evaluating constraint functions, the evaluation being based at least in part on a channel deformation criteria.
Claims10
A method of evaluating a proposed solution to a nuclear reactor constraint problem, comprising:
- providing an objective function definition generic to constraint problems, the generic objective function definition being a sum of a first number of credit terms plus a sum of a second number of penalty terms, at least one of the second number of penalty terms being based on a channel deformation criteria;
- configuring the generic objective function into a nuclear reactor constraint problem objective function;
- receiving a value of at least one variable in at least one credit term in the configured objective function, the credit term variable being related to the proposed solution;
- receiving a value of at least one variable in at least one penalty term in the configured objective function, the penalty term variable being related to the proposed solution;
- and
- generating a figure of merit for the proposed solution based on the credit term variable and the penalty term variable using the configured objective function.
