11. Assume that a firm's total cost function is the same as above example. 12. K-trivial sets are characterized by obedience to the Standard cost function , defined by 13. Therefore, the players maximize the mathematical expectation of the cost function . 14. Let be the fitness or cost function which must be minimized. 15. Different cost functions and different strategies were used to optimize a many-body trial-function. 16. Subadditivity is an essential property of some particular cost functions . 17. Interestingly, while mathematicians prefer to work with convex cost functions , economists prefer concave ones. 18. It is often the case that the constraints are interchangeable with the cost function . 19. For example, suppose we have a stochastic programming problem with a submodular cost function . 20. It might even be possible to construct separate cost functions .
