netlogo

I'm replicating a small piece of Sugarscape agent simulation model in Python 3. I found the performance of my code is ~3 times slower than that of NetLogo. Is it likely the problem with my code, or can it be the inherent limitation of Python? Obviously, this is just a fragment of the code, but that's where Python spends two-thirds of the run-time. I hope if I wrote something really inefficient it might show up in this fragment: UP = (0, -1) RIGHT = (1, 0) DOWN = (0, 1) LEFT = (-1, 0) all_directions = [UP, DOWN, RIGHT, LEFT] # point is just a tuple (x, y) def look_around(self): max_sugar_point

upon compilation I receive an error message saying set is the wrong commander before patch size 10 what commander should I use instead and why? globals[road?] to setup clear-all ask patches [set pcolor green] end to go if mouse-down? [ ask patch mouse-xcor mouse-ycor [ edit-world ] end to edit-world if EDIT_TOOL = "Road" [set pcolor grey set patch-size 10 ] end The right command is set-patch-size , with the hyphen after set . Patch-size can not be changed programatically but only in settings. All patches have the same size. What are you trying to do simulation wise with that line? Patch-size

See the code below intended for determining the number of settled turtle clusters (Red and grey turtles) out of a number of randomly distributed non-settled turtles (black), as well as the maximum, minimum and mean cluster size (radial extent) in a netlogo world/ interface. globals[ cluster-size cluster-count cluster-size-growth cluster-count-growth ] to setup clear-all ask patches [ set pcolor white ] create-turtles 1000 [ set color black set label-color blue setxy random-xcor random-ycor set cluster-size 1 ] ask n-of 5 turtles [ ask turtles in-radius one-of [1 2 3] [ set color one-of [red

For my maze project, I want to create a monitor button that keeps track of how long it takes for the turtle to get from start to finish. How would I code for the timer? Check out reset-timer and timer and in the docs. During maze setup, do a reset-timer . During the running of maze you can check on elapsed time with timer If you mean how many patches passed in moving to the target, you can use following: turtles-own [target move-counter] to Your-Move-Function let t target face min-one-of all-possible-moves [distance t] fd 1 set move-counter move-counter + 1 end 来源： https://stackoverflow.com

I'm trying to assign turtles a number which I can tell them to move in order of. Using previous posts and some general playing around I've managed to create a ranked order list of the turtles, but now I want to assign turtles a number based on their relative position in that list. Example: current list: [(turtle 8) (turtle 1) (turtle 9) (turtle 0)] desired turtle designation: turtle 8 = 1, turtle 1= 2, turtle 9 = 3, etc. So far I've reached: globals [rank_list] turtles-own [var. rank] set rank_list sort-on [var.] turtles create-turtles (50) [setxy (random-float max-pxcor) (random-float max
