FoldIt's Undo menu has a graph which shows the recent scores your structure has had when you made a move. This graph has two important features that make it suitable for use as an extremely accurate score monitor: it updates "live" as your structure moves, and it scales to fit your lowest and highest recent scores. It is much more sensitive than the progress bar next to the score.

This method will not reveal much useful information if you make large nudges that drop the score by hundreds of points, but is the key to making slow steady increases in your score, even when the increases are in the tenths, hundredths or even thousandths of a point.

Graph Properties memory allocation

In the graph properties you can allocate memory and indicate how many 'undos' you would like to see on the graph. A setting of 75-90% is comfortable for most computers and most puzzles when you want to use the graph as described below.

If you experience unexpected crashing or are not using the graph, a safer setting is 25% x 25 particularly on large puzzles, or puzzles with heavy constraints.

How To Set Up and Use The Undo Graph

1) "Clear" the graph by pressing the "Clear" button. This resets the scale of the graph so that you can see even small score changes clearly.

2) Right-click on a piece in your structure and choose Wiggle from the popup menu. This move is called a local wiggle and will only affect that piece, which usually results in a small score change. You might also try locking off a small section of two or three pieces and pulling on it.

3) The end of the graph will jump all the way up or down, since the graph contains only two different scores.

4) Stop the wiggle and do it again, or something similar. This will put a third value into the graph and might show you some movement in the score so you can get a feel for how the graph moves "live" as the calculations take place.

You may see the graph spike high, then drop down again. FoldIt remembers any spike during calculations as your new "best"; you don't need to stop exactly on that spike.

5) Continue making moves and observe how the graph changes.

Do a Restore-Best after any move that raised the score. This ensures that your next move is building on the best score that your structure "passed through" while the last move took place.

If any large score changes are made, the graph is much less useful, since most of the scores will be squeeze into an almost flat line to make room for the large change. It is useful to undo over big drops in score and make a different move; this will keep the graph sensitive to small moves.

The Local Wiggle Strategy depends heavily on using this technique.
