Challenge
Forsyth–Edwards Notation (FEN) is a standard notation for describing a particular board position of a chess game. Your challenge is to evaluate the score using the FEN string. This is an example of a FEN string:
5k2/ppp5/4P3/3R3p/6P1/1K2Nr2/PP3P2/8
Using this string, you can calcula...
When implementing an algorithm for correcting aliased measurement data, I hit the need to implement following function. The function takes input bitstring on the left, and should produce the integer and list on the right:
1 => 1, [0]
10 => 1, [0]
11 =>Anonymous
In linear algebra, the permanent of a square matrix is a function of the matrix similar to the determinant. The permanent, as well as the determinant, is a polynomial in the entries of the matrix. Both permanent and determinant are special cases of a more general function of a matrix called the immanant.

The permanent of an n-by-n matrix A = (ai,j) is defined as

In linear algebra, the computation of the permanent of a matrix is a problem that is known to be more difficult than the computation of the determinant of a matrix despite the apparent similarity of the definitions.
The permanent is defined similarly to the determinant, as a sum of products of sets of matrix entries that lie in distinct rows and columns. However, where the determinant weights each of these products with a ±1 sign based on the parity of the set, the permanent weights them all with a +1 sign.
While the determinant can be computed in polynomial time by Gaussian elimination, th...
