  Multiset - Wikipedia, the free encyclopedia
In mathematics, a multiset (sometimes also called a bag) differs from a set in that each member has a multiplicity, which is a natural number indicating (loosely speaking) how many times it is a member, or perhaps how many memberships it has in the multiset.
A submultiset (B, n) of a multiset (A, m) is a subset B ⊆ A and a function n : B → N such that n(a) ≤ m(a).
The cumulant-generating function of the multiset of sums of elements of two multisets of numbers is the sum of the two cumulant-generating functions.

 Amenable number - Wikipedia, the free encyclopedia
An amenable number is an integer for which there exists a multiset of as many integers as the original number that can be either added up or multiplied together to give the original number.
All composite numbers would be amenable if the multiset was allowed to be of any length, because, even if other solutions are available, one can always make an inelegant solution by taking the prime factorization (expressed with repeated factors rather than exponents) and add as many 1s as necessary to add up to n.
Because of the multiplicative identity, multiplying this set of integers will yield n no matter how many 1s there are in the set.

 multiset - Dev Shed
multiset C programming forum discussing all C derivatives, including C#, C++, Object-C, and even plain old vanilla C. These languages are low level languages, and used on projects such as device drivers, compilers, and even whole computer operating systems.
If you were not aware of it, the multiset is implemented as a red-fl tree.
That's because the second parameter of a multiset<> is a function object.

 Multiset
Formally, a multiset consists of a set S and a function m(x) that maps each element x of S to the number of times it occurs in the multiset.
The Multiset interface extends the Collection interface, adding methods for getting the number of distinct elements and the number of times a given element occurs in the multiset.
An entry is a pair (e, n) where e is an element of the multiset and n is the number of times e occurs in the multiset.

 Problem Set   (Site not responding. Last check: 2007-10-13)
A multiset (or bag) is a set that may contain more than one occurrence of a particular element.
multisets are useful for a variety of purposes; for example, keeping track of histograms during experimental measurements.
We expect your implementation to be reasonably efficient, especially for multisets with many occurrences of the same element; the run-time efficiency will carry some weight but will be a secondary consideration.

 Info on Multisets
A multiset is like a set, except that repeated elements are allowed.
When referring to permutations of a multiset we assume that the elements of the multiset are 0,1,..., t, that the number of occurrences of i is n
If S is a multiset, then such k-subsets have several applications, notably in statistics, where they arise in permutation tests with repeated data values and as 2 x n contingency tables.

Constructs an empty multiset which will use the optional relation comp to order keys, if it is supplied, and the allocator alloc for all storage management.
iterator erase(iterator first, iterator last); Providing the iterators first and last point to the same multiset and last is reachable from first, all elements in the range (first, last) will be deleted from the multiset.
For example, if your compiler does not support member function templates, you can construct a multiset in the following two ways: int intarray[10]; multiset first_multiset(intarray, intarray +10); multiset second_multiset(first_multiset.begin(), first_multiset.end()); but not this way: multiset long_multiset(first_multiset.begin(),first_multiset.end()); since the long_multiset and first_multiset are not the same type.

Background: A multiset (or bag) is a set that may contain more than one occurrence of a particular element.
Note that multiset do not keep track of any ordering of their elements, so the multisets {1,2,2,3} and {2,3,1,2} are equal.
Multisets are useful for a variety of purposes; for example, keeping track of a collection of experimental measurements.

The multiset, as a set with multiplicities associated with its elements in the form of natural numbers, is a notation which has appeared again and again in various areas of mathematics and computer science.
As a data structure, multisets stand in-between strings/lists, where a linear ordering of symbols/items is present, and sets, where no ordering and no multiplicity is considered.
All in all, the book assesses the state of the art of the notion of multisets, the mathematical background, and the computer science and molecular computing relevance.

Multiset is used to handle such aspect of the system.
Basically a multiset is very similar to an array indexed by a scalarset, except that the "multiset index" cannot be stored in any state variable and most of the local variables.

I have tried nearly every macro based script recorder available, but none could do what I needed the most: install an application not based on time, but rather the state of the buttons in the install window.
Multiset's recording and playback are exceptional, accurate, and most important, not based on time, so the scripts will work on any computer regardless of speed.
All you have to do is to install the application only once on your PC and MultiSet will record all your actions.

 [Coq-Club] Multiset order.   (Site not responding. Last check: 2007-10-13)
There is a nice proof of well-foundedness of multiset order due to Wilfried Buchholz presented by Tobias Nipkow (http://www4.informatik.tu-muenchen.de/~nipkow/misc/multiset.ps).
However it uses induction on the size of multiset which is impossible to perform with this definition (the problem is somehow more serious because this definition allows infinite multisets in general which is undesirable in this case of course).
Is there any chance to stick to library definition of multisets, like, let's say, by refining it somehow (how?) to finite multisets in a way that allows induction on their size?
