The Ikeda Delay Differential Equation model shows the dynamics of a delay differential equation that depends on the value of the dynamical variable x(t) at a previous time x(t-τ).  Sprott shows that these systems provide elegant examples of chaos in systems that are too simple to exhibit chaos without the time delay.  This model demonstrates how EJS provides a natural syntax for implementing these models.

The Ikeda Delay Differential Equation Model was developed using the Easy Java Simulations (EJS) modeling tool version 4.3.3.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_chaos_IkedaDDE.jar file will run the program if Java is installed.
