Each test contains multiple test cases. The first line contains the number of test casestt(1≤t≤6681≤t≤668). Description of the test cases follows. The first line of each test case contains a single integernn(2≤n≤1002≤n≤100) — the length of the permutation. ...
This paper introduces a geometrical model which reduces the general three-dimensional packing problem to a finite enumeration scheme; a very efficient algorithm is derived. Several tests prove the validity of the algorithm, in particular a numerical estimate of the asymtotic performance bound is given...

For a warm start, set iA0(i) == true to start the algorithm with the ith inequality constraint active. Use the optional output argument iA from a previous solution to specify iA0 in this way. If both iA0(i) and iA0(j) are true, then rows i and j of A should be linearly indep...
His goal is to reach the position right after the rightmost character of the string. In one jump the Grasshopper could jump to the right any distance from 1 to the value of his jump ability. The picture corresponds to the first example. The following letters are vowels: 'A', 'E', 'I...
We exploit the community structure of graph to find the influential communities, and then find the influence of each node as a combination of its local and global influences. We compare our algorithm with the state-of-the-art methods for influence maximization problem and the results of our ...
