A method for improving web search results based on analysis of users' offline activities that are related to their online search. Web search results, including local search results, for a user may be improved by monitoring the actions of users when not interacting with the web search engine. By monitoring “offline” activities (e.g., telephone calls) and matching a person participating in an activity (e.g., the person making a telephone call) to a search engine user, a set of preferences for a given user may be determined, which may be used to select and sort web search results for that user. Preference data for one user may be used to select and sort web search results for other users, including those for which the search engine does not have preference data.

In a network router, a tree structure or a sorting network is used to compare scheduling values and select a packet to be forwarded from an appropriate queue. In the tree structure, each leaf represents the scheduling value of a queue and internal nodes of the structure represent winners in comparisons of scheduling values of sibling nodes of the tree structure. CBR scheduling values may first be compared to select a queue and, if transmission from a CBR queue is not timely, a packet may be selected using WFQ scheduling values. The scheduling values are updated to reflect variable packet lengths and byte stuffing in the prior packet. Scheduling may be performed in multiple stages.

Systems and methods to solve combinatorial problems employ a permutation network which may be modeled after a sorting network where comparators are replaced by switches that controllably determine whether inputs are swapped or are left unchanged at the outputs. A quantum processor may be used to generate permutations by the permutation network by mapping the state of each switch in the network to the state of a respective qubit in the quantum processor. In this way, a quantum computation may explore all possible permutations simultaneously to identify a permutation that satisfies at least one solution criterion. The Travelling Salesman Problem is discussed as an example of a combinatorial problem that may be solved using these systems and methods.
