But while such problems are in general computationally intractable, it is seldom necessary to determine the Pareto optimal set exactly.
In order to search for the global optimal solution exactly, one of the evolutionary algorithms, differential evolution (DE) algorithm is employed based on the constructed Kriging surrogate model.
When these requirements cannot be satisfied exactly, optimal (approximate) solutions are sought.
Without eliminating the self-interference, with the condition of the imperfect CSI, the exactly optimal solution is difficult to obtain.
The space agency says it opted for the spot due to surface geography, even while solar conditions aren't exactly optimal.
Of course, a temporary work-around isn't exactly optimal, nor is is something you should have to do after having shelled out nearly $3,000.
In order to achieve a tractable inference of cost-based abduction, we aim at obtaining a nearly, rather than exactly, optimal solution.
For (u le r), optimal fixed compensation exactly resembles Proposition 4. This observation is due to the fixed compensation (hat{beta }_1 = hat{b}_1 = 0) in both cases.
Since the exactly optimal solution for this practically appealing problem is intractable, we first propose optimizing the source, relay, and receiver matrices in an alternating fashion.
Instead, as Google confirmed to us earlier today, it uses Apple's relatively slow UIWebView to render web pages and that sadly means the browsing experience on iOS isn't exactly optimal.
