prod() duplicates the update's sector production code, except it
computes both output with present materials ("make" output) and output
not limited by lack of materials or production backlog ("max" output).
It also rounds materials consumed up instead of randomly.
Factor prod_output() out of produce() for reuse by prod(). prod()
runs it twice: once for "make" output and once for "max" output.
Test output changes are due to random rounding.

The collection value of a sector is
sector value = sector type value * (sector efficiency + 100)
+ sum of item values
item value = item type value * amount
The sector and item type values are configurable.
The item type collect values aren't too far off the power values:
uid mnem pow val pow/val
0 "c" 50 1 50
1 "m" 100 0 inf
2 "s" 125 5 25
3 "g" 950 60 15.8
4 "p" 7 4 1.75
5 "i" 10 2 5
6 "d" 200 20 10
7 "b" 2500 280 8.9
8 "f" 0 0 NaN
9 "o" 50 8 6.25
10 "l" 20 2 10
11 "h" 40 4 10
12 "u" 50 1 50
13 "r" 50 150 0.33
The power value is very roughly ten times the collect value, except
for civilians and uw it's 50, for rads its 0.33, and military are free
to collect. The latter two make no sense.
Replace the item type collect value by the power value / 50 for
people, and by the power value / 10 for everything else. This makes
collecting military, shells, guns and uw more expensive, and petrol,
bars, iron, oil and rads cheaper.
The sector type values are basically arbitrary. For instance, an iron
mine costs five times as much as a wilderness, but a third of an
uranium mine, regardless of actual resource contents.
Replace this by different arbitrary values:
sector value = (item value of materials necessary to build it
+ build cost) * efficiency / 100
+ sector type maximum population
+ sum of item values
Some sector types become cheaper, some more expensive.
Drop sect-chr and item selector value.

Replace the term
power value of materials and cost + 9
by
power value of materials and cost + maximum population / 1000 * 8 + 1
The value of ordinary sectors (maximum population 1000) doesn't
change. The stock game's mountains, plains and bridges are now worth
only 28% as much.
This concludes my tweaking of the power factor for now. I tested it
with data from a real game (Hvy Metal II). The effect is small: #5
overtakes #4, and the lead of #1 over #2 and #3 shrinks some. Closer
analysis finds the following reasons. The game had very expensive big
cities. Valuing them correctly gives countries with many cities a
noticeable boost. Planes are worth less than before, but the
difference is much larger for cheap planes. Big piles of construction
materials are worth much less, and shells, guns and bars are worth
more.

Building sectors can make you rate *lower* on the power chart, because
the power factor treats all sectors the same, regardless of build
materials and cost.
To avoid that, replace the term
efficiency / 10.0
by
(power value of materials + power value of cost + 9)
* efficiency/100.0
The value of ordinary sectors, which take no materials and cost $100,
doesn't change. The stock game's fortress is now worth 80% more due
to its materials and higher cost. The stock game's wilderness is
worth 10% less, because it costs nothing.

Chainsaw 3 added the designate cost along with extra build cost and

cost and materials, the cost to designate didn't pass the test of
time: it was set to zero in Empire 2. Get rid of it.

Items, ships, planes and land units all contribute to the power
factor, which determines position on the power chart.
Items are worth
amount * item value * (0.5 + nation tech level / 1000.0)
The item values aren't quite right: producing stuff can *hurt* your
position on the power chart. Food, uw and rads are worth nothng.
Reduce the value of oil, and give rads the same value as oil. Tweak
value of iron and oil products so that production's power change is
roughly zero around p.e. 0.9 (tech 110), except for construction
materials, where it's zero at p.e. 0.5 (tech 0). Construction
materials become less valuable, shells, guns and petrol become more
valuable. Increase value of bars to roughly match the other changes.
It may still be too low. Halve the value of civilians, and give the
other half to uw. Results:
old new change
civ 100 50 / 2
mil 100 100
shell 80 125 * 1.5625
gun 400 950 * 2.375
pet 2 7 * 3.5
iron 10 10
dust 200 200
bar 1000 2500 * 2.5
food 0 0
oil 100 50 / 2
lcm 100 20 / 5
hcm 200 40 / 5
uw 0 50 new
rad 0 50 new
Ships, planes and land units are worth
base value * effic/100.0 * (0.5 + unit tech level / 1000.0)
For ships and land units, the base value is
lcm/5.0 + hcm/5.0
Build cost is ignored, but lcms are valued twice as much "loose" ones
(before this commit). Therefore, building stuff can change your
position on the power chart in both directions, depending on the type
of build.
For planes, the base value is
20 * (0.5 + nation tech level / 1000.0)
Build cost and materials are ignored, and tech is squared. This
is plainly absurd.
Unify to
(power value of money and materials to build) * effic/100.0
This formula is chosen so that building stuff doesn't change your
power factor. Bonus: it doesn't assume anything about possible build
materials.
For ships and land units, factoring in build cost overcompensates the
discounted value of construction materials more often than not.
Noteworthy changes for the stock game:

ss slave ship 20 5.8 * 0.29 largest decrease

meng mech engineer 3 45.4 * 15.13 largest increase
For planes, the power value change depends on the type. Below a
certain nation tech level, planes of this type become more valuable,
above less.
For the stock game, planes costing at most $1000 become less valuable
at any nation tech level that can build them, and planes costing at
least $1800 become more valuable at any practical tech level,
i.e. under 400. Noteworthy planes:
plane type new
sam Sea Sparrow 2.1 least valuable

Actual abilities of ships, planes and land units depend almost
completely on the individual unit's tech, not the nation's tech. The
power factor should reflect that.
The power value of a unit is of the form
base value * (20 + nation's tech level) / 500
Change it to
base value * (20 + unit's tech level) / 500
Note that a plane's base value still depends on the nation's tech
level. This commit merely makes the absurdity stand out a bit more.
To be fixed later.

In the old times, power didn't consider tech at all. Chainsaw's
option NEWPOWER (mandatory since v4.2.14, on by default before)
changed this dramatically: the power factor gets multiplied by
max(1, tech) / 500.
In the early game, small absolute tech differences yield large power
factor differences. For instance, if country A has tech level 10, and
B has 5, then A gets a factor two boost.
As the game progresses, tech differences between viable countries tend
to grow, but only slowly. The influence on power diminishes. For
instance, if C has tech level 270 and D has 240 (quite a respectable
tech lead), then C gets a modest 1.125x boost over D.
Change the factor to (20 + tech) / 500. Now A's advantage is only
1.2, and C's is 1.115.
You might think that's rather low. However, tech is not power unless
you project it, and then it manifests itself as sectors, population
and other stuff power counts.
The same tech term occurs in plane power, except with just tech
instead of max(1, tech) . Change it there as well, for consistency.

If option RES_POP is enabled, the power factor is multiplied by a
"research factor" of 1.0 + maxpop / 10000.0, where maxpop is the
maximum population of a mine sector.
Back when this code was written (Chainsaw 3), all sectors had the same
population limit, so using a mine sector was as good as any. Since
then, it has become configurable, and the stock game has both sector
types with lower (mountains, plains) and with higher (cities)
population limits.
Space for people is worth considering for power, but multiplying total
power by a fudge factor based on the most common sector type's maximum
population is silly. Drop it.
Adjusting each sector's value for maximum population would make more
sense, with and without RES_POP. Perhaps later.

Optional arguments can save typing. Mandatory arguments are more
easily discoverable: just run the command and answer its prompts.
Empire traditionally uses optional arguments only for expert features.
Consider mission:
[0:640] Command : mission
Ship, plane or land unit (p,sh,la)? s
ship(s)? 0
Mission (int, sup, osup, dsup, esc, res, air, query, clear)? int
operations point? .
frg frigate Early Bird(#0) on an interdiction mission, centered on 21,-3, radius 0
1 ship
Compare retreat:
[0:638] Command : retreat
ship(s)? 0
shp# ship type x,y fl path as flt? flags
0 frg frigate 21,-3
1 ship
Arguments are not discoverable this way.
Change retreat to work like mission: make the second argument
mandatory, and if it's 'q', show retreat orders, else treat it as path
and ask for conditions:
[0:637] Command : retreat
ship(s)? 0
Retreat path, or q to query? jj
Retreat conditions ('?' to list available ones)? i
shp# ship type x,y fl path as flt? flags
0 frg frigate 21,-3 jj i
1 ship

The capability to navigate ships spread over several sectors is
obscure and rarely useful. Accidental use is probably more frequent
than intentional use. Issues:
* Interactive prompts show only the flagship's position, and give no
clue that some ships are actually elsewhere.
* Path finding is supported only when all navigating ships are in
the same sector.
* Interdiction becomes rather complex. For each movement, every
sector entered is interdicted independently. This means the same
fort, ship, land unit or plane can interdict multiple times.
Interdiction order depends on the order the code examines
ships. which the player can control. This is all pretty much
undocumented.
* Complicates the code and its maintenance. Multiplies the number of
test cases needed to cover navigate.
