Scientists have developed an exact approach to a key quantum error correction problem once believed to be unsolvable, and have shown that what appeared to be hardware-related errors may in fact be due ...

The paper presents a new dynamic direction restricted algorithm based on the Dijkstra algorithm, direction restricted algorithm and area restricted algorithm for computing shortestpath from one node ...

An efficient and flexible algorithm is presented for finding a k shortest loopless path with distinct initial links from one node to each other node. Low-order polynomial bounds are established for ...
