Constructor Detail

RandomWalkGraph

public RandomWalkGraph(int n,
               double p)

This general constructor creates a new random walk graph on a specified interval with a specified probability of a step in the positive direction.

Parameters:

n - the number of steps in the random walk

p - the probability of a step to the right

RandomWalkGraph

public RandomWalkGraph(int n)

This special constructor creates a new symmetric random walk graph on a specified interval. Thus the probability of a step in the positive direction is 0.5.

Parameters:

n - the number of steps in the random walk

RandomWalkGraph

public RandomWalkGraph()

This default constructor creates a new symmetric random walk graph on the interval [0, 10].

Method Detail
