Patent number: 11514782Abstract: A method involves accelerating the electronic determination of high quality solutions to routing problems by utilizing determined optimized time windows for precomputing optimal path matrices to reduce computer resource usage. The use of traffic windows defined based on changes in rates of change of speeds for traffic on road segments allows for more rapid determination of a set of one or more high quality solutions as compared to requiring on-demand, in-process determination of a shortest path for a particular time during comparison of paths or routes performed as part of a process for determining high quality solutions to the routing problem.Type: GrantFiled: December 31, 2018Date of Patent: November 29, 2022Assignee: salesforce.com, inc.Inventors: John Brian Stewart, Dinesh Premalal Weerapurage, Timothy Alan Carnes, Christopher Sebastian Groer, Lahiru Sandakith Pileththuwasan Gallege, Chenlu Lou

Patent number: 11359925Abstract: A method involves accelerating the electronic determination of high quality solutions to routing problems by leveraging simplified travel time approximations. The use of first approximation travel time estimates allows for more rapid beginning of a process for electronically determining one or more high quality solutions to a routing problem as compared to having to wait for computation of second travel time estimates for every ordered pair of locations involved in the routing problem, thus allowing for more rapid determination of one or more high quality solutions.Type: GrantFiled: September 17, 2019Date of Patent: June 14, 2022Assignee: salesforce.com, Inc.Inventors: John Brian Stewart, Dinesh Premalal Weerapurage, Timothy Alan Carnes, Christopher Sebastian Groer, Lahiru Sandakith Pileththuwasan Gallege, Chenlu Lou

Patent number: 11215463Abstract: A method involves utilizing a geo-locator service and zone servers to reduce server resource requirements for determining high quality solutions to routing problems. The use of a geo-locator service and zone servers enables the use of servers having less memory which can handle determination of high quality solutions to routing problems involving locations spanning a smaller geographic area even if they are incapable of handling determination of high quality solutions to routing problems involving locations spanning a larger geographic area, and enables efficient assignment of requests to an appropriate server without unduly burdening high value servers having sufficient memory to handle determination of high quality solutions to routing problems involving locations spanning a very large geographic area with determination of high quality solutions to routing problems involving locations spanning a smaller geographic area.Type: GrantFiled: December 31, 2018Date of Patent: January 4, 2022Assignee: salesforce.com, Inc.Inventors: John Brian Stewart, Dinesh Premalal Weerapurage, Timothy Alan Carnes, Christopher Sebastian Groer, Lahiru Sandakith Pileththuwasan Gallege, Chenlu Lou
