Random Walk 1D Continuous Model
written by Wolfgang Christian
The EJS Random Walk 1D Continuous Model simulates a 1-D random walk with a variable step size. You can change the number of walkers and probability of going right and left. You can modify this simulation if you have Ejs installed by right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item.

The Random Walk 1D Continuous Model was created using the Easy Java Simulations (Ejs) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_stp_RandomWalk1D.jar file will run the program if Java is installed.  Ejs is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models.  Additional Ejs models are available.  They can be found by searching ComPADRE for Open Source Physics, OSP, or Ejs.

Please note that this resource requires at least version 1.5 of Java (JRE).

First Walker doesn't move

Author: Holger Becker

With the default setting #=1, the Walker doesn't move. With #=2 only one Walker moves, the other standing still at 0 etc.

To change this:

Decrease i under Evolution

for(int i=0; i

Random Walk 1D Continuous Model:

Covers the Same Topic As STP Random Walk 1D Continuous Program

The Open Source program, part of a package of resources for Statistical and Thermal Physics, provides a similar simulation.
