Cost per research point calculator
 

Hi there,

I hacked together a small webpage which calculates and compares the gold cost per research point given different researchers/magic scales/number of turns.

Here it is, in the hope that someone else might find it useful:

Comments are very welcome, but bear in mind that I havent used any effort on the layout or stuff like that... :-)

Cheers,
Thomas

Re: Cost per research point calculator
 

REALLY interesting, thank you!

I'm suprised that there is something that is actually worse than Niefel Jarl http://forum.shrapnelgames.com/images/icons/icon7.gif

Addendum:

It also seems that Niefelheim is the worst possible nation (Excluding AE and SG ermor http://forum.shrapnelgames.com/images/icons/icon10.gif )for magic research in a non-drain scale... A VERY good reson to take some magic.

Re: Cost per research point calculator
 

Nice work...

Re: Cost per research point calculator
 

lol, when you set it to drain 3, the witch doctor lists 'infinite' in gold cost/RP http://forum.shrapnelgames.com/images/icons/icon7.gif .

Re: Cost per research point calculator
 

uummmm....Ctis lies on the avarage scale. The Empoisoner do well I see...


Nice work by the way! http://forum.shrapnelgames.com/images/icons/icon7.gif

Re: Cost per research point calculator
 

yeah, you should change all the "infinite" results to account for the fact that the minimum RP/turn is 1.

Re: Cost per research point calculator
 

Does your calculator take into account upkeep? Because that makes sacred units much more efficient.

Re: Cost per research point calculator
 

Nicely done. Good work.

Re: Cost per research point calculator
 

Oh, the Warlock Apprentice is Abysia's cheapest researcher in the short-term but the Demonbred is cheaper over the long term thanks to being sacred. That never even occured to me. I've just been building Apprentices. Now I wonder if the higher upfront cost of the Apprentice is worth more than the long term savings of the Demonbred. On default Magic, it takes 20-30 turns to see it though.

Thanks a lot for this thing. At first I thought it wasn't that useful, but it really is.

Re: Cost per research point calculator
 

<font size="2" face="sans-serif, arial, verdana">Definitely does. Also takes into account Ulm Master Smiths being immune to drain. Pretty robust little calculator.

Re: Cost per research point calculator
 

Glad people like it - now I might actually bother with the layout of the page (at some point) http://forum.shrapnelgames.com/images/icons/icon7.gif

<font size="2" face="sans-serif, arial, verdana">Doh, I did not know that. It should be fixed now http://forum.shrapnelgames.com/images/icons/icon7.gif

Anyway, upkeep with sacred units benefitting should be included. And I actually made this whole thing since I was also wondering about those abysian troops.

Re: Cost per research point calculator
 

<font size="2" face="sans-serif, arial, verdana">Don't! Keep it simple, there's no need for anything fancier...

I suppose experience isn't taken into account?

Re: Cost per research point calculator
 

As the exact question I was coming to find out was bard vs sidhe champ in upkeep, thanks for the very timely table!

As an additional question though, how does the game calculate those percentages of an upkeep. i.e. on magic 3 a bard is 1.25, sidhe is 1.33. Is there any effective difference between them or do they just get counted as 1 each turn or 2 each turn or does it actually charge the extra gold every 4 turns for bard and 3 for sidhe?

This table also makes me cry http://forum.shrapnelgames.com/images/icons/icon9.gif As my beloved Tuatha I'm required to take a magic scale and I get the 47th best researcher? bah! Some "magical theme" we are. Bards were teachers and history keepers etc weren't they? (or am I just messed up through too many different books!) Give em a 1 point research bonus! http://forum.shrapnelgames.com/images/icons/icon7.gif

Re: Cost per research point calculator
 

<font size="2" face="sans-serif, arial, verdana">I would imagine that it adds up the upkeep for all units keeping the decimal points, then just drops whatever is left at the end. I know that it does store the decimal points up to the very end though, as the devs have mentioned this.

Re: Cost per research point calculator
 

Is base Man theme missing?

Re: Cost per research point calculator
 

My two favorite Neutrals aren't there, Wizard and Witch! Witch is 100 gold for 4 base research.. sacred. I forget Wizard.. been a while since I found one.

I too noticed that base Man was missing.

Re: Cost per research point calculator
 

<font size="2" face="sans-serif, arial, verdana">Wizard is 140 for 10 research. Less interesting than a Sage, even in Drain3 environment .
However Wizards can be really good researchers for those poor nations with ultra-expensive mages (Abysia anyone ? http://forum.shrapnelgames.com/images/icons/icon12.gif )

Experience is not taken into account, but it should of course! Very good point. Does the manual mention how much xp is gained from researching? Oh well, I guess its time to RTFM...

<font size="2" face="sans-serif, arial, verdana">wups... no longer http://forum.shrapnelgames.com/images/icons/icon7.gif

<font size="2" face="sans-serif, arial, verdana">Well, independents are incomplete for now. I have added the witch, and if anyone want anything else added, just tell me their stats.

I will of course add independent researchers myself as I encounter them from now on.

Just for the record, the way I calculate upkeep is the initial cost divided by 15 (and half of that for sacred units). I keep all decimal points all the time.

Re: Cost per research point calculator
 

<font size="2" face="sans-serif, arial, verdana">Ok, added.

(non-sacred I assume)

Re: Cost per research point calculator
 

Ok I have looked in the manual and made a quick search here on the forum, but I am not sure I fully understand experience in the context of research.

What I gathered so far was:

Units level at 15, 50, 100, 200 & 400 xp (and no more?).

Each level gives +1 to research.

Each unit automatically gets +1 xp each round.

But does a unit not gain some "research xp" or some such in addition if it is just hanging around doing research?

Hopefully someone can clarify this so I can take experience into account in the calculations http://forum.shrapnelgames.com/images/icons/icon7.gif

Re: Cost per research point calculator
 

Lore master 150 gold 12 research

Possibly the best Drain 3 researcher in the game

Re: Cost per research point calculator
 

Fix: The C'Tis shaman is sacred (currently it seems non-sacred and similar to the empoisoner), which helps C'Tis somewhat on a longer time scale.

Re: Cost per research point calculator
 

<font size="2" face="sans-serif, arial, verdana">hmmm... all I can say to this is what Graeme Dice said a few Posts ago:

<font size="2" face="sans-serif, arial, verdana">Of course, whatever method is actually used in-game is what should go into the calculator. Does anyone know for sure?

Also, I am still hoping that someone could clarify whether or not a unit gains experience for researching (in addition to the 1xp/turn that every unit apparently gets).

Re: Cost per research point calculator
 

<font size="2" face="sans-serif, arial, verdana">Don't believe they do. Researchers I keep at home studying never gain levels very fast, and I've never had one go past two stars. But they do gain experience faster if they get involved in a skirmish or two.

Re: Cost per research point calculator
 

<font size="2" face="sans-serif, arial, verdana">It's in the wish list thread that no rounding occurs till the very end.

I have added XP into the picture now - of course assuming that the units are doing nothing but researching from the day they are created (in a real game this does not have to be so of course). The extra XP not surprisingly give an advantage to low cost/low research level researchers in the long run compared to higher cost/higher research level ones.

Re: Cost per research point calculator
 

IIRC, all commanders (and possibly units too, never bothered to check) gain 1 XP per turn just by doing anything not XP related (i.e. not fighting, or entering war academy, and not enhanced by items). So A researcher would gain 1 XP per turn, whether she researches or not.

For example, in my long SP testing game as Atlantis, which finally ended on turn 221, all mages in my capitals were ofLevel 3 & 4, whom I know were hired in the early days to fuel my research. And since I was the only water nation, these mages never seemed battle at all (sitting home and hit books). So this seems to collaborate my memory that commanders gain 1 XP per turn at minimum, as some of these researchs would get 200+ XPs (level 4), while the rest were level 3, as observed.

Just an observation.

Re: Cost per research point calculator
 

The research formula:

Research = Sum of all mage levels + 2 + Experience bonus +/- Sage bonus/Witchdoctor penalty +/- Scale adjustment + Item bonuses

Mage levels are all magic paths except divine and unholy. Commanders without any mage levels can't research at all. Includes bonuses from path boosting items (e.g. Earth Boots).

Experience bonus is +1 rp per star.

Sage bonus - various units have this including sages, loremasters, the Great Sage pretender, adepts of the metal orders. I think it's +3 for most of those units, but I'm not sure of the exact value. There's also a heroic research bonus, I think - I assume this works like the sage bonus, I don't know if it's cumulative with a sage's natural bonus if a sage gets the heroic research ability.

Witchdoctor penalty - I've heard that they are bad at research now but haven't played Machaka recently.

Scale adjustment - +1 RP/magic scale, -1 RP/drain scale. Ulm Master Smiths ignore drain but do benefit from magic (but Ulm pretenders are affected normally).

Item bonuses - various items give RP bonuses of different sizes.

Research can't be reduced below 0 but can be reduced to 0 (non-experienced level 1 mage in drain-3).

Re: Cost per research point calculator
 

<font size="2" face="sans-serif, arial, verdana">Commanders that don't list a research ability can't research. Arco Golden era philosophers have no magic ability, but can still research.

<font size="2" face="sans-serif, arial, verdana">Witchdoctor's now research at a base level of 3, instead of the 5 they would normally have with three magic skills.

<font size="2" face="sans-serif, arial, verdana">I take it you've never played a drain 3 nation. The minimum research value is 1, and never lower than that.

Re: Cost per research point calculator
 

<font size="2" face="sans-serif, arial, verdana">Added. (and its even the best drain 2 researcher http://forum.shrapnelgames.com/images/icons/icon7.gif )

<font size="2" face="sans-serif, arial, verdana">wups. Fixed.

Hmm... maybe I should add a way to show the data I am using so its easier for people to spot my bugs http://forum.shrapnelgames.com/images/icons/icon7.gif

Update: The calculator now includes a link to a page which shows the unit data that is used for the calculations.

Re: Cost per research point calculator
 

How is maintenance cost calculated ?
In the game it's surely rounded (up or down) somewhere, to have entire figures. I've heard that it was done on a per unit basis, so that can really change the values on the long run (50-100 turns).
Anyone has the formula ? IW only ? http://forum.shrapnelgames.com/images/icons/icon12.gif

Re: Cost per research point calculator
 

Thanks for the corrections - I quickly learned not to play Drain 3 except with standard Ulm, and I forgot about the Philosophers - and for the data on Witch Doctors (who must therefore have a "sage bonus" of -2).

Re: Cost per research point calculator
 

Hi,

Just wanted to mention that I believe that the calculator (here) really does every calculation in agreement with the discussions in this thread.

Also, I added a few more independents.

Cheers,
Thomas
