New Wheel Generator 1.8.5.1 and GAT Engine 3.0.2 versions

Post by lottoarchitect » Sat Feb 08, 2020 10:01 pm

New versions of these programs were made available today.

The changes mostly include known bug-fixes. Most notably, we hopefully have addressed this error message "Ordinal X not found" which shows up on some installations. Please let us know if you had that error and if it is gone after this update.

For GAT Engine 3.0.2, we have addressed a known bug which could not save in a state the retained GAT IDs if added via the panorama menu. This also results in an incompatibility vs GAT 3.0 state files which can't be loaded in the new GAT.

Wheel Generator 1.8.5.1 has some more extensive changes. Addressed a bug which connected the priority sliders to the bias operation. This fix resulted in some more changes: we have re-introduced the bias multiplier mechanism. At the optimization panel we now have a list of various settings ranging from x0.0001 up to x10000. The default setting x1 is the same as WG 1.8.5. The other settings are useful in various more "extreme" constructions. Bigger than x1 is mostly useful in coverings having too many blocks (in the range of thousands), and coverings having t<<m e.g. 3if6 constructions. Smaller values like x0.01 etc are mostly useful in coverings which include normal guide filters. As usual the whole point in optimization is to let the coverage fluctuate a bit. Use the bias multiplier to have the slider in a more "correct" range to operate on. Always start with x1 and adjust as needed if required.
Along the lines of setting a correct bias, we also introduce a new indicator at the progress panel. At the end of the improvements line we now have an extra value which indicates how many different blocks have been altered by the engine over the last [ b ] (total blocks of the covering) changes. Values in the range of 1-3 usually indicate a "stuck" condition by the engine, i.e. the engine only changes up to just 3 different blocks which is usually a cycle between these blocks therefore a stuck condition. We usually aim to have a value greater than 5.
Please also check the help file for more info on these new features.

Is out there any video showing how to use WG ?

Hi Bruxo, in its simplest form WG is very simple to operate. Set the v,k,t,m and an initial b parameter and click optimize. The idea in covering is to reach coverage to 100% (or less if we aim for open-cover constructions). The only crucial part of user's intervention is to adjust the engine bias (at the optimisation panel). The optimization logic is you should let the engine fluctuate the coverage a bit which allows room for the engine to introduce even "bad moves" which later on usually result in an even better coverage. Experimenting with bias will give a rough idea on what bias to set.
Finally, if no matter what we do we cannot bring an improvement the typical adjustment is to add more blocks to the covering and continue optimization and repeat that process till we reach the desired coverage.
A more thorough explanation of the v,k,t,m parameters alongside how to adjust the bias (the optimization panel) is available at the help file.

Now, WG has a lot of features and can cater for different constructions possible but the main idea of the optimization is the above. The more you use WG, the more you'll understand the logic behind it and make even better constructions. I could make a video saying "set v,k,t,m and b here, then click optimize". Doesn't sound like a useful video really. I can understand the visual aspect of seeing this and possibly I may produce one at some time.
