11 Electrical and Computer Engineering Data Flow

12 Electrical and Computer Engineering Progress  Improved algorithm run time Within specifications for 20 tasks Implemented Point Pairs Table to improve runtime  Google Calendar Synchronization Table view that displays Google Calendar Events to quickly add tasks from  Additional Data Points Increased the accuracy of routing and timing

13 Electrical and Computer Engineering Algorithm Optimization  PointPairs Table Pathing between nodes is now O(1) Generating PointPairs table is O(N 2 )  Scheduling Heuristic Use subset of campus to estimate schedules 10x increase in performance, still O(S 2 +SH) complexity  Meets 3 second specification up to 20 tasks Avg. scheduling time at CDR: 12.5 sec Avg. scheduling time currently: 2.1 sec

17 Electrical and Computer Engineering Current Deployment Plan  Alpha version released Received user feedback Implemented suggestions from user feedback  Preparing the app store release  We plan making updates as necessary after app store release, based on user reviews

18 Electrical and Computer Engineering Deployment Plan (app store release)  App store release will require a thorough cleaning of the source code  Fix any remaining memory leaks and user interface bugs

19 Electrical and Computer Engineering Demo Day Expectations  Application demonstration at demo day  App store release  App awareness, marketing and distribution to new students / visiting students
