We conduct an experiment to explore the range of the outcome if we put the parameters we pop in to a range. Example: create-turtles 100 setxy random-float max-pxcor random-float max-pycor distributes 100 turtles randomly in the first quadrant These. ifelse count my-links > 2 ifelse random-float 1.0.

I do not know whether A is linked to B or C), is there anyway to match A to B and B to A as a pair then set the same random-float 1 value Thanks.

That is, I can use gis:intersecting to give a variable to those patches that fall within the GIS My rationale for this is related to this question I posted before (NetLogo - applying values to patches within polygons).

I then import the GIS file back into NetLogo using the GIS extension. I then use the R extension in NetLogo to create a minimum convex polygon (MCP) surrounding each territory and export those polygons as a shapefile. NetLogo - misalignment with imported GIS shapefiles Question I've got a NetLogo model in which each animal occupies a "territory", wherein all patches that belong to the animal are the same color as the animal.

NetLogo : How to make sure a variable stays in a defined range? Question I have a few variables which can be inherited to child agents by a variation of + 0.1 and -0.1 or without any changes, or random again, What I have done is like this: (The code is just an example) to reproduce ask turtle 1 ] end Currently I have to check if X of child turtle is always within range by something like this: if X > 1 if X 0 [ let candidates other people with [ count my-links 10,000s of patches, turtles)? How can I speed up a model that runs very slowly? Answer1 We just published an article on execution speed of NetLogo it is available at: The article's main points are (a) NetLogo is not necessarily slow for executing large scientific models, and in fact has speed advantages over some alternatives and (b) NetLogo models do often execute very slowly at first but can almost always be sped up dramatically by using a few basic techniques.

prints a normally distributed random floating point prints an exponentially distributed random floating 3.1 random-integer-between 3.2 random-number-between. Random-poisson reports a Poisson-distributed random integer. The set of NetLogo commands and reporters has been extended by the Behaviour Composer. 2) Please be aware that NetLogo turtles will follow a random order each time to do the commands. You did the ifelse correctly, but then the if is not. The algorithm of random generates a uniform distribution. If you need to generate floating point numbers, you should use random-float. random only generates positive integer numbers. Random-normal reports a normally distributed random floating point number. IF needs a true or false statement and 'random-float 1' is not true or false. For example, if we wanted to generate a random floating point number between 4 and 7, we could write the following code: 4 + random 3. (Note: for results with a given mean and variance, use inputs as follows: alpha = mean * mean / variance lambda = 1 / (variance / mean).)

Turtles are agents that move around in the world. In NetLogo, there are three types of agents: turtles, patches, and the observer. Each agent can carry out its own activity, all simultaneously. Agents are beings that can follow instructions. Random-gamma reports a gamma-distributed random floating point number as controlled by the floating point alpha and lambda parameters. Random Numbers Strings Turtle Shapes File I/O Agents The NetLogo world is made up of agents. It is equivalent to (- mean) * ln random-float 1.0. Random-exponential reports an exponentially distributed random floating point number. (The standard deviation may not be negative.) (which reports a random floating point number) or random-normal (which. Reports an accordingly distributed random number with the mean and, in the case of the normal distribution, the standard-deviation. NetLogo is a programmable modeling environment for doing agent-based simula. These dots should then be able to transform back into rays and leave the patches in the certain area. When a ray (turtle) hits the patches it should either be absorbed or transformed into heat dots. The model should represent different surfaces in the city and their albedo.
