### infinite research in marathon (math!)

**Thu Dec 07, 2017 9:28 am**for regular mode analysis, visit viewtopic.php?f=5&t=48597

after some google search, im surprised i cant find the raw material for each science pack.

so i do some calculations and share them here.

1gas ≈ 1.111crude

1light ≈ .7407crude

1heavy ≈ .5555crude

1coal ≈ 3.889crude

or inversely, 1crude = 1.8heavy = 1.35light = .9gas = (9/35 ≈ .2571)coal

these directly come from advanced oil processing, coal liquefaction, cracking and simple algebra.

i will use these conversion to convert oil product into crude oil in next section.

oil : converts gas, light and heavy to crude.

coal (+oil) : converts crude to coal and add to coal cost. this assumes all oil product come from coal liquefaction.

interesting note: copper is used more than iron during infinite research.

as a bonus, since we have the ratio of gas, light and heavy, we can figure out the ratio of refinery and each cracking chemical plant

(by using the power of ALGEBRA).

Advanced Oil Processing

>>adv oil process : heavy to light : light to gas = 31025 : 3453 : 20751 ≈ 9 : 1 : 6

>>a set of 9:1:6 consume 180crude/s and produce 149gas/s + 18.5light/s + 1.333heavy/s (or 0.173862 total sp/s, bottlenecked by gas)

>>to reach 1 total sp/s, 52 : 6 : 35 is required (rounded up).

Coal Liquefaction

>>coal liq : heavy to light : light to gas = 31025 : 3618 : 9104 ≈ 17 : 2 : 5

>>a set of 17:2:5 consume 34coal/s and produce 109.67gas + 13.5light/s + 0.667heavy/s (or 0.088889 total sp/s, bottlenecked by heavy)

>>to reach 1 total sp/s, 133 : 16 : 40 is required (rounded up).

feel free to correct any mistake.

##### 1. Oil conversion

1gas ≈ 1.111crude

1light ≈ .7407crude

1heavy ≈ .5555crude

1coal ≈ 3.889crude

or inversely, 1crude = 1.8heavy = 1.35light = .9gas = (9/35 ≈ .2571)coal

these directly come from advanced oil processing, coal liquefaction, cracking and simple algebra.

##### 2. Research Cost

oil : converts gas, light and heavy to crude.

coal (+oil) : converts crude to coal and add to coal cost. this assumes all oil product come from coal liquefaction.

interesting note: copper is used more than iron during infinite research.

##### 3. Crack Ratio
