Highlight to read.</div><div style=\"padding:4px;border:1px solid #888;\"><br />The generation process will always be denser towards the origin. Branches will generally go outward. There are very few correct branches that go towards the origin. Because you're going up and to the right, all branches after a few squares, will tend to go up and to the right (it looks like lightning). This does not help the decision process when moving from the origin to the cheese. However, if you look at the cheese and search for a path to the origin, branch points will either move away from the origin or towards it. Choosing the one that tends towards the origin is correct 95% of the time and you can trace backwards through the whole maze in a matter of about 10 seconds. When you get to a point where you can see the clear path between your current point you're looking and the location of the mouse, move the mouse along the path until you forget the solution path, and then repeat the process. After a couple of tries, I could do this in about 3 passes and solve it in about 30 seconds. <br /><br />Possible optimization to the generation process to negate this method:<br /><ul><li> in a first pass, choose about a dozen points randomly scattered through the screen.</li><li> create the solution path that winds through these points. Very windy. All sorts of directions.</li><li> Create some number of branches off this path using the existing algorithm.</li></ul></div></div>", "user": "blake" }, { "id": "978791", "time": "1522652106", "html": "Clever, clever...<br /><br /><a href=\"https://i.imgur.com/YBp4vnK.png\">Difficulty increased!</a>", "user": "hydrogen777" }, { "id": "978792", "time": "1522653170", "html": "I approve.<br /><br /><a href=\"https://i.imgur.com/R1Lv1Lg.png\">This was the best I could do</a><br /><br />Feature requests!<br /><ul><li> When encountering a dead end (or when a 3-walled dead end can be seen from the mouse's current position) that tile changes color to dark blue and the route back continues to change to dark blue until you get to the last branch. </li><li> More branches?
