Path Planner/Compression Best-first-search. ● 100 bits instead of 100 integers to represent maps. ● Resulting compression per map is a 93.75% savings. ● Tours are still full-length 1-D arrays: gives us an order in which to traverse map. ● 4x4 Grid: ● {{ 0, 0, 0, 0 }, { V, B, B, 0 }, {0, B, V, 0 }, { 0, 0, 0, 0 }} <-- 32 bytes 1-D Array: ● { 0,0,0,0,V,B,B,0,0,B,V,0,0,0,0,0 } <-- 32 bytes 1-D Bitset of Obstacles: ● 0000 0110 0100 0000 <-- 2 bytes 1-D Bitset of Victims: ● 0000 1000 0010 0000 <-- 2 bytes Savings: 4 bytes / 32 bytes = 87.5% Compression ●
