Wrong comments on mines-sarsa?

[Alejandro]

Hi:

I think the comments that explain the meaning of the actions in the mine-sarsa-* examples are wrong. For example this is from
svn/trunk/projects/packages/examples/mines-sarsa-python/sample_mines_environment.py :

(lines 177 to 187)

		if (theAction == 0):#move down
			newCol = self.agentCol - 1;

		if (theAction == 1): #move up
			newCol = self.agentCol + 1;

		if (theAction == 2):#move left
			newRow = self.agentRow - 1;

		if (theAction == 3):#move right
			newRow = self.agentRow + 1;

I think changing the value of the columns corresponds to left/right movement, and changing the value of the rows corresponds to up/down movements (the opposite of what the comments say).

Alejandro.

You're probably right, those comments could be updated to be more
intuitive if they don't correspond to what the viewer shows. Other
than that it's really fairly arbitrary.
