Question

Hi,
I'm on ps6. I've written the RunSimulation() method, but I'm not getting anywhere near close the number of clock cycles as they get in the handout ( I get ~40 vs their 150).

http://pastebin.com/kfF32kcp here is my code. Sorry it's a bit messy.

Answer 1

i'll comment on all i see:
-do lines 70 and 73 work?
-what does line 94 do?
- you should delete all those 'raise NotImplementedError' lines
-108 thru 111; you don't need the if/else just 'return self.tile in self.cleaned'
-153 thru 156 ditto
-259 thru 265; what if the second attempt hits a wall? - you might be cleaning tiles that aren't in the room
-line 307; bots is a list just iterate over it -> for bot in bots:
-311/312; the built-in function sum() takes an iterator -> time_sum = sum(times)

Answer 2

Hi,

Thanks for the help. Corrected most of the points you raised. Except
-259 thru 265

I'm assuming changing direction takes a time-step. I guess up to 75% of the possible new directions can still lead to hitting a wall. maybe ill change that.

At the moment I'm getting well above what the brief quotes for times. Swings and round abouts.

Answer 3

Ok, deleted last comment as it was wrong, must have mistaken which shell was running the solution and my code.

Turned out I needed to treat the percentage done as a float. Not sure why that made a difference

Answer 4

I misunderstood your op - i thought your were getting less, faster times

integer division in 2.x --> truncates the fractional part of the results

Answer 5

no you understood right. it became longer times because when i calculated the percent done it was always 0 except when all tiles were done, 1.
