Selected cost functions to translate continuous traits into payoffs. Enum on steroids. Currently available cost functions are:

0

Linear cost function (independent of opponent): \(C(x,y)=c_0\,x\).

1

Quadratic cost function (independent of opponent): \(C(x,y)=c_0\,x+c_1\,x^2\).

2

Square root cost function (independent of opponent): \(C(x,y)=c_0 \sqrt{x}\).

3

Logarithmic cost function (independent of opponent): \(C(x,y)=c_0 \ln(c_1\,x+1)\).

4

Exponential cost function (independent of opponent): \(C(x,y)=c_0 (1-\exp(-c_1\,x))\).

10

Linear cost function (sum of focal, \(x\), and opponent, \(y\), traits): \(C(x,y)=c_0 (x+y)\).

11

Quadratic cost function (sum of focal, \(x\), and opponent, \(y\), traits): \(C(x,y)=c_0 (x+y)+c_1 (x+y)^2\).

12

Cubic cost function (sum of focal, \(x\), and opponent, \(y\), traits): \(C(x,y)=c_0 (x+y)+c_1 (x+y)^2+c_2 (x+y)^3\).

13

Quartic cost function (sum of focal, \(x\), and opponent, \(y\), traits): \(C(x,y)=c_0 (x+y)+c_1 (x+y)^2+c_2 (x+y)^3+c_3 (x+y)^4\).

20

Linear cost function (cross terms of focal, \(x\), and opponent, \(y\), traits): \(C(x,y)=c_0\,x+c_1\,y+c_2\,x\,y\).
