월드오브탱크 사용자들이 게이밍 지수 낸다고 만든 공식 처럼..

가중치 넣고, 여러가지 변수 통제하면서 적절한 추천 지수 만들면 될듯.

The Steps of WN8 - The FormulaStep 1rDAMAGE = avgDmg / expDmg rSPOT = avgSpot / expSpot rFRAG = avgFrag / expFrag rDEF = avgDef / expDef rWIN = avgWinRate / expWinRate


Step 1 takes the counts of tanks played on account, and multiplies them by the expected stats to get the account total expected values. Then the actual account totals (your total dmg, frags, spots, def, win-rate) are divided by the total expected values to give the ratios.

Step 2rWINc = max(0, (rWIN - 0.71) / (1 - 0.71) ) rDAMAGEc = max(0, (rDAMAGE - 0.22) / (1 - 0.22) ) rFRAGc = max(0, min(rDAMAGEc + 0.2, (rFRAG - 0.12) / (1 - 0.12))) rSPOTc = max(0, min(rDAMAGEc + 0.1, (rSPOT - 0.38) / (1 - 0.38))) rDEFc = max(0, min(rDAMAGEc + 0.1, (rDEF - 0.10) / (1 - 0.10)))


Step 2 sets the zero point for the ratios. See the assumptions section for more info on why this happen. min and max are functions to ensure the ratios stay within bounds. The constants are in the format of


(rSTAT – constant) / (1 – constant)


To normalize that, a player with all rSTATSc = 1 would receive 1565 WN8. A player with all rSTATS = 1 would also have all rSTATSc = 1 because (1-c)/(1-c) = 1.

Step 3

WN8 = 980*rDAMAGEc + 210*rDAMAGEc*rFRAGc + 155*rFRAGc*rSPOTc + 75*rDEFc*rFRAGc + 145*MIN(1.8,rWINc)
