Re: [nbos] Astrosynthesis on Windows 7 64-bit

This is my platform, and it runs well, but I have given up on using the sector generator. Even at the lowest possible setting of systems, and asking it not to generate any system contents, I have encountered the following:

Any sector size above a couple of hundred light years takes hours, and hours, and days - and eventually uses up all of the 8GB of RAM in my box and freezes even a Win7 64bit machine
Any serctor size, even with selecting the least number of systems possible, crams stars so close you do not need a star ship to travel to them, you could probably just walk there.

My comments to the first point are: Why? It's just creating a random point (not even asking it to generate any system details) - yet it takes hours and hours. Do not even try a sector with a 5000 light-year radius!

To the second point, I dont think the System Frequency slider is working properly - or if it is it needs adjusting. I see no real difference in seperation distances at minimum setting or maximum, especially the larger the sector generated. Every star is crowded so close its like the galactic center at rush hour. On the plus side, no need for wormholes, warp drives, or hyper generators, just a jet pack and a space suit and you can colonize the thousands of planets within 10LY (see the three examples below). i think that the slider, needs to be adjusted.

Test One
My three examples generating a 10 LY radius sector, using the Astrosynthesis Beta 4 generator:

Min setting: 206 systems, average distance*: 3.8 LY
Default setting: 1240 systems, average distance*: 2.4 LY
Max Setting: 2129 systems, average distance* 1.6 LY

We see the 'Min' setting generates about 16% of the default's total number of systems, while the 'Max' setting generates 171%. However, the average distances do not seem to reflect the same spread. I think that there should be some minimium distances for each point on the slider.

Test Two
My next example: Generating a sector of 5000 systems,using the Astrosynthesis Beta 4 generator:

5000 system bodies created
resulting sector size is: 17 LY radius
Average distance* between bodies: 2.3 LY

In this example, the generator is cramming things so closely together it is ridiculous. There is no way to get 5000 systems spread out in a larger sector.

Conclusion and Recomendation
Using our own galactic neighborhood as a typical example, our closets steller neighbor is 4.2 LY away. The generator seems to be putting every generated sector at a point somewhere in the galactic core - where the super massive blackhole, rapid steller birth and dstruction, would make life impossible. I think the system placement slider's "default" seting should be whatever is the logic applied for the Min setting; with approriate adjustments for Min, Max, and in between positions. This would render a more "believable" or "realistic" steller neighborhood as a default.

If using the Select Number of systems option: It would be nice if I could specify the number of systems and the minimum distance between bodies, or a way to tell the generator to spread the systems out over a given sector size, say 5000 systems in a 50 LY radius sector.

*Average distance was computed slecteing 10 system pairs and using these as the sample data to determine distance between system bodies
