11. 11 Electrical and Computer Engineering Data Flow

12. 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. 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
