  Decision problem - Wikipedia, the free encyclopedia
In this sense, a decision problem is equivalent to a formal language.
A function problem consists of a partial function f; the informal "problem" is to compute the values of f on the inputs for which it is defined.
Every decision problem can be converted into the function problem of computing the characteristic function of the set associated to the decision problem.

 Function problem - Wikipedia, the free encyclopedia
Function problems are more awkward to study than decision problems because they don't have an obvious analogue in terms of languages, and because the notion of reduction between problems is more subtle as you have to transform the output as well as the input.
For all function problems there is an analogous decision problem such that the function problem can be solved by polynomial-time Turing reduction to that decision problem.
This places the traveling salesman problem in the complexity class FP (the class of function problems which can be solved in polynomial time on a deterministic Turing machine with an oracle for a problem in NP), and in fact it is complete for that class.

 Encyclopedia :: encyclopedia : Computational complexity theory   (Site not responding. Last check: 2007-10-31)
After the theory explaining which problems can be solved and which cannot be, it was natural to ask about the relative computational difficulty of computable functions.
The time complexity of a problem is the number of steps that it takes to solve an instance of the problem as a function of the size of the input (usually measured in bits), using the most efficient algorithm.
A decision problem is a problem where the answer is always YES/NO. For example, the problem IS-PRIME is: given an integer written in binary, return whether it is a prime number or not.

 Dreams: The Case Against Problem-Solving
First, it is one thing for a dream to "reflect" a problem; it is quite another for it to offer a "solution." Second, a distinction has to be made between solutions that are present within a dream, on the one hand, and waking realizations that are based upon thinking about the dream on the other.
Recognizing the problems with theories that attribute a waking function to the very few dreams that are recalled, there are now several theorists who claim that dreaming has a function even when dreams are not recalled.
If the weaknesses of all theories of dream function are combined with the evidence that dreaming is a process that occurs only in human beings, and only after the age of 5 or 6, then it seems highly unlikely that dreams have any adaptive function.

 The Forwarding Problem: Arguments
The problem has two sides: first, f must be able to accept an arbitrary argument list and forward it to E (relatively) unmodified, so that the meaning of E does not change as a result, and second, f must be able to return the result of E back to its caller.
An esoteric problem with this approach is that it is not possible to form a const reference to a function type, but this will be addressed by Core Issue 295.
A perfect forwarding function would forward rvalue arguments as rvalues; none of the methods described so far achieve this, since it is not possible to determine from within a function whether an argument was an l- or an rvalue.

 Problem Spot   (Site not responding. Last check: 2007-10-31)
In logic, a decision problem is determining whether or not there exists a decision procedure or algorithm for a class S of questions requiring a Boolean value (i.e., a or, or or).
The name “frame problem” derives from a common technique used by animated cartoon makers called framing where the currently moving parts of the cartoon are superimposed on the “frame”, which depicts the background of the scene, which does not change.
Even after that, however, the term “frame problem” was still used, in part to refer to the same problem but under different settings (e.g., concurrent actions), and in part to refer to the general problem of representing and reasoning with dynamical domains.

 Flash Kit Community Forums - function problem
This function will make a movie clip rotate backwards and forwards once the counter variable hits a certain number (the variable 'delay'), and rotate at a certain speed ('speed') - which will either be 1 or 2)).
Problem is I can't seem to get the individual movieclip to respond without writing the function on the movieclip itself, the function is currently on the main timeline.
The reason that it shakes the entire movie is because the function is defined on the main timeline.

Q- Find the slope of the tangent line for the function y2 = x2 - x4 at (0, 0), also explain what is going on at the origin.
This problem is one that makes use of the concept of implicit differentiation.
Note that this is not really a function in the strictest sense of the word, since you get two values of y for almost every value of x you plug in.

 Iterated analytic function problem
Author: existing If you consider a point in a space to represent a real-valued function can one generate an operator which takes a point in the space to another point such that the orbit generated when the operator is iterated covers a ball of points.
Yes, an operator maps a function to a function; the operator you describe is very specialized, in that its "domain" is f, f(f), f(f(f)), etc. Thus, a given function f completely specifies both the operator and its domain.
Similarly, orbits of size 2 are fixed points of the function f(f(x)), and orbits of neighbors may be attracted to these size 2 fixed points.

 Finitism in Geometry
The problem one faces there is precisely to set up a translation from a classical geometrical model to a model whereof the domain (usually) consists of the finite set of pixels or cells that make up the computer screen.
Three problems of this sort will be discussed: the distance function problem, the dimension problem and the isotropy problem.
Once adjacency has been stipulated, a distance function can be easily derived: the distance between p and q, d(p,q), is the smallest number of “links” in a chain of points connecting p and q such that each one is adjacent to the previous one.

So when the playhead inside MC1 reaches the 15th frame (where the code was) a function is attached to MC1 that tells it to do this: with every passing frame from now on set a variable in this timeline called 'callm1' to equal 'true'.

 Custom Function #Name Problem - Excel Help Forum
Some time ago, I created a custom function to calculated the number of days sales that can be covered by the current inventory balance (commonly known as Days on Hand).
The function essentially figures out how many months of demand the inventory can cover and then multiplies this by an array of days in each month.
The function has been a huge time saver, but obviously is of little use if it isn't reliable.
