  • Patent number: 8700417
    Abstract: To perform a query, a set of nodes for an origin is loaded, it is determined if a node is a destination for each node of the set of nodes, and a path is recorded in response to the node being the destination. A hypothetical path is generated in response to the node not being the destination, it is determined if the hypothetical path exceeds a stopping rule, and the hypothetical path is recorded in response to the hypothetical path not exceeding the stopping rule.

  • Patent number: 8255250
    Abstract: To determine if an intermediate stop in a multistop travel itinerary is a layover or an intermediate destination, a passenger utility value is calculated for the intermediate stop and the passenger utility value for the intermediate stop is compared to a passenger utility for a layover. The intermediate stop is determined to be a layover in response to the passenger utility value for the intermediate stop being greater than or equal to the passenger utility for a layover and the intermediate stop is determined to be an intermediate destination in response to the passenger utility value for the intermediate stop being less than the passenger utility for a layover.
