--costfcn <f1[,f2[...]]>

cost function for each trait:

0: $C(x,y)=c_{0}x$

costs linear in own investment $x$.

1: $C(x,y)=c_{0}x+c_1{x}^2$

costs quadratic in own investment $x$ (default).

2: $C(x,y)=c_0\sqrt{x}$

$\sqrt{}$-saturating costs for own investment $x$

3: $C(x,y)=c_0\ln (c_{1}x+1)$

$\ln$-saturating costs for own investment $x$

4: $C(x,y)=c_0(1-\exp (-c_{1}x))$

$\exp$-saturating costs for own investment $x$

10: $C(x,y)=c_0(x+y)$

costs linear in joint investments $x+y$.

11: $C(x,y)=c_0(x+y)+c_1(x+y{)}^2$

costs quadratic in joint investments $x+y$.

12: $C(x,y)=c_0(x+y)+c_1(x+y{)}^2+c_2(x+y{)}^3$

costs cubic in joint investments $x+y$.

13: $C(x,y)=c_0(x+y)+c_1(x+y{)}^2+c_2(x+y{)}^3+c_3(x+y{)}^4$

costs quartic in joint investments $x+y$.

20: $C(x,y)=c_{0}x+c_{1}y+c_{2}xy$

costs linear in investments $x$ and $y$ as well as cross term $xy$.
