The problem of calculating angle is a standard application of Hansen's resection. Such calculations can establish that ∠ B E F {\displaystyle \angle {BEF}} is within any desired precision of 30 ∘ {\displaystyle 30^{\circ }} , but being of only finite precision, always leave doubt about the exact value.

One of the simplest APX-complete problems is MAX-3SAT-3, a variation of the Boolean satisfiability problem.In this problem, we have a Boolean formula in conjunctive normal form where each variable appears at most 3 times, and we wish to know the maximum number of clauses that can be simultaneously satisfied by a single assignment of true/false values to the variables.
Here’s another problem that’s very easy to write, but hard to solve. All you need to recall is the definition of rational numbers. Rational numbers can be written in the form p/q, where p and ...
Typically such limits show a factor of approximation beyond which a problem becomes NP-hard, implying that finding a polynomial time approximation for the problem is impossible unless NP=P. Some hardness of approximation results, however, are based on other hypotheses, a notable one among which is the unique games conjecture.
The W hierarchy is a collection of computational complexity classes. A parameterized problem is in the class W[i], if every instance (,) can be transformed (in fpt-time) to a combinatorial circuit that has weft at most i, such that (,) if and only if there is a satisfying assignment to the inputs that assigns 1 to exactly k inputs.
A final issue raised by multiple reviewers is inertia: supposing for the sake of argument that these methods are better, are they sufficiently better to make worthwhile the large individual effort of re-learning geometry and trigonometry in these terms, and the institutional effort of re-working the school curriculum to use them in place of ...
The Pentagon has failed its annual financial audit for the seventh year in a row. This means the Department of Defense (DOD) has failed every single audit it has been subjected to, but officials ...
