Drop down and go to the right. Go to the first upward facing shaft. Jump up and grab the switch. Go to the right and go the first octagonal opening. Wait there for a drone to pass over your head. Continue right, grab the switch there, and drop down, then head right. Grab the switch in the octagon to your left. Jump up and get the switch in the octagon above you and to your left. Return to the last key you just got, drop down through here, and go left. Grab the switch here. Drop down. Go to the left, until you reach the door opener.
Do a perpindicular jump, and go all the way to the top of this shaft. Drop into the octagonal space on your left. Perform another perpindicular jump through the shaft above. Head left to the exit.
In computer science, a heuristic algorithm or simply a heuristic is an algorithm that ignores whether the solution to the problem can be proven to be correct, but which usually produces a good solution or solves a simpler problem that contains or intersects with the solution of the more complex problem. Heuristics are typically used when there is no known way to find an optimal solution, or when it is desirable to give up finding the optimal solution for an improvement in run time.
