Description
This applet allows you to construct an NFA over the alphabet {a,b}, and visualise the simulation of the NFA with various input strings.

• Transition Function: The choice boxes with the yellow background allow you to define the transition function (including multiple, null, epsilon transitions) for each state and each input symbol. Click the 'Update' function after defining each transition.
• Final State: Select the final state from the choice box with the green background, and click the 'Update' button.
• Input String: Specify an input string using symbols a, b in the textfield, and click the 'Start' button to start the simulation.
