* While the decision problem is NP-complete the optimization problem is NP-hard, its resolution is at least as difficult as the decision problem, and there is no known polynomial algorithm which can tell, given a solution, whether it is optimal ( which would mean that there is no solution with a larger, thus solving the decision problem NP-complete ).

While the more general approach of such adaptive systems is more suitable for real-world problem solving, it has far less to do with the traditional artificial intelligence connectionist models.

While it is possible to define some arbitrary, ad hoc cost function, frequently a particular cost will be used, either because it has desirable properties ( such as convexity ) or because it arises naturally from a particular formulation of the problem ( e. g., in a probabilistic formulation the posterior probability of the model can be used as an inverse cost ).

While studying the continuum hypothesis, Cohen is quoted as saying in 1985 that he " had the feeling that people thought the problem was hopeless, since there was no new way of constructing models of set theory.

While repeating the earlier stories, the later sources of Suetonius and Cassius Dio provide additional tales of insanity.

While it may be mathematically possible to construct such a system, it is not clear what additional explanatory power or physical insight such a system would provide, assuming that it does indeed accord with existing empirical data.

While IMAP remedies many of the shortcomings of POP, this inherently introduces additional complexity.

While the number of users is below the congestion point, each additional user adds additional value to every other customer.

While arm power, accuracy, and pocket presence – the ability to successfully operate from within the " pocket " formed by his blockers – are still the most important quarterback virtues, the ability to elude or run past defenders creates an additional threat that allows greater flexibility in the team's passing and running game.
