Re: Synthesising Oscillators

That's what I was thinking of. Thanks. Didn't occur to me to look a little deeper and see if there was anything that required two steps, where the first step adds to what is to be removed. The second step I have is slightly different. Only advantage is that this one is quicker. x=10, y=18 4bo$5b2o$4...

Also brought the number of constructions to over 7000, and added several hundred construction component categories. Database si...

Re: Synthesising Oscillators

If there's a way to covert a [8.5] to [10.4], then it should be possible to convert the [14P2.18] into [16P2.79]. Similarly, a conversion in the other direction could reduce [18.475] . x=29, y=81 10bo$8b3o8b2o$7bo10bo2bo$8bo10bobo$5bo2bo7bo2bob2o$4bob2o7bob2o$4bo10bo$3b 2o9b2o6$10bo$8b3o7b2o$7bo9bo2...

You might want to consider further reducing these collisions.

Version 1.0.1 is available. The database now has all stable objects to 20 bits, and oscillators and spaceships to 100. Includes another 100 Glider constructions, and fixed some bad entries.

Also, by request, object views include a link to their Catagolue page.
