Re: Nearest polar opposite economies

I should probably Javascript anyway at some point. I don't know if I should do it now.

Re: Nearest polar opposite economies

I'm not so sure I want to get hosting space and learn Javascript just for this purpose. I will, however, do custom calculations for whoever wants them.

Re: Nearest polar opposite economies

Ok. To do this properly, you need to use the game distance formula which is not exactly euclidian. It's 0.4*math.floor(sqrt(dx*dx + dy/2*dy/2)) in pseudo language. Dividing y coordinates by 2 is just scaling, but rounding the sqrt with floor makes the difference. That is interesting. The imperfect ...

Re: Nearest polar opposite economies

Out of interest, what are those numbers representing as they seem to not be game distances? Relative Euclidean distance based on the following: http://wiki.alioth.net/index.php/Oolite_planet_list/Galaxy_1 For a sense of scale, at a relative distance of about 15 there is a pretty comfortable amount ...

Nearest polar opposite economies

As is well known, trading is (generally) most profitable between Poor Agricultural and Rich Industrial planets. I have been doing "milk runs" between Sotiera and Inera and this has been going well but I wondered if I could do better. It turns out that I could These are the 10 closest pairs...

A couple are off by a tenth. You can get exact figures by looping over the masked MARKET_RND byte for each economy, no Monte Carlo required.
I'll be damned.

Re: Monte Carlo estimation of best commodity profits

They start to use tonnage if you have more than a ton of gold/platinum aboard. I thought they started to use hold space if you have more than 499kg aboard - but I may be wrong. Yes, metric ton(ne)s (or TC). In that case, one need only multiply by the appropriate factor. The expected profit moving a...

Re: Monte Carlo estimation of best commodity profits

So I decided that I would run the calculation of price for each kind of commodity in each economy 10,000 times to average out the randomness... Um, forgive me please if I sound dismissive (or pig ignorant), but does the market creation algorithm not produce a normal distribution of price results? I...

Re: Monte Carlo estimation of best commodity profits

Thanks for that! Interesting to see that illegal items are not even the most profitable. That depends. I haven't taken rock hermits into account. And, though slaves are not quite as profitable as might be expected—I wouldn't deal in them anyway—the other two forms of contraband have a wide margin o...

Monte Carlo estimation of best commodity profits

I have been using and like this Javascript utility: http://rockthehalo.org.uk/oolite/OoliteCommodityCalculator.html But there's a very important thing it doesn't tell me. It does not tell me the expected (i.e. average) price of a unit of a given commodity, only gives me the spread of possible values...

Re: Swap roll and yaw in options screen

True but the current proposal is a decent stand-in. Making a generic keyboard configuration utility would require a new interface, this just requires another menu item and a teeny bit of backend. If I knew Objective C and version control as well as the etiquette of working on these sorts of projects...

Re: Swap roll and yaw in options screen

Yaw is very much an in-atmosphere flight control. In a gravity-free vacuum with no horizon, it's redundant: pitch and roll is all you need. There's no difference between yawing to starboard, and rolling 90° to starboard and pitching up (or rolling 90° to port and pitching down). Orienting objects o...

Re: Swap roll and yaw in options screen

In any case, the "canon" is not beyond reproach. Indeed! Perhaps if the player had to enable yaw, then NPCs could have it enabled too? However, I know that I'm in the minority in supporting equality for NPCs. I would say that equality or inequality for NPCs is not simply a matter of what ...

Elite was not like most space sims - it had no yaw.
I'm willing to bet this primarily had to do with a) the necessity of docking with stations having artificial gravity and possibly b) software or hardware limitations at that time. In any case, the "canon" is not beyond reproach.
