What is dot?

Dot is a program that performs graph layout and can generate an X-windows based display of a graph from a text input file. Various extensions have been implemented in QSIM that make use of this capability. These extensions have been developed for our private use at UT, but we are distributing them due to their usefulness. Currently, Dot is used for the following two purposes:

1.

To generate a graphical description of a QDE along with qualitative value information for a specified state if desired.

2.

To generate a graphical ``explanation'' of why there does not exists a successor that matches a specified template for a given state. This is called successor explanation and it is described in the qsim-extensions document.
