I've been trying to create a 2D random walk process for my project. The question is as follows, Create a 2-dimensional random walk process where the walker can move up, down, left, or right. The walker should have an equal chance of going in any direction (25%). Create a graph of a single walk.
We've been using these functions but I'm unsure how to go about it correctly.
`A = Table[0, {1}, {2}];
Do[
x = RandomReal[];
Which[
x < 0.25, A[[i + 1, 1]] = A[[i, 1]] + 1;
x < 0.25, A[[i + 1, 2]] = A[[i, 2]] - 1],
{i, 1, 0}, {i, 1, 1}]
ListLinePlot[A]`
It's supposed to look like this. Thanks
