- --benefitfcn <f1[,f2[...]]>
- benefit function for each trait:
- 0: \(B(x,y)=b_0\ y\)
- benefits linear in opponents investment \(y\).
- 1: \(B(x,y)=b_0\ y+b_1\ y^2\)
- benefits quadratic in opponents investment \(y\).
- 2: \(B(x,y)=b_0 \sqrt{y}\)
- \(\sqrt{\ }\)-saturating benefits for opponents investment \(y\)
- 3: \(B(x,y)=b_0 \ln(b_1\ y+1)\)
- \(\ln\)-saturating benefits for opponents investment \(y\)
- 4: \(B(x,y)=b_0 (1-\exp(-b_1\ y))\)
- \(\exp\)-saturating benefits for opponents investment \(y\)
- 10: \(B(x,y)=b_0 (x+y)\)
- benefits linear in joint investments \(x+y\).
- 11: \(B(x,y)=b_0 (x+y)+b_1\ (x+y)^2\)
- benefits quadratic in joint investments \(x+y\) (default).
- 12: \(B(x,y)=b_0 \sqrt{x+y}\)
- \(\sqrt{\ }\)-saturating benefits for joint investments \(x+y\)
- 13: \(B(x,y)=b_0 \ln(b_1\ (x+y)+1)\)
- \(\ln\)-saturating benefits for joint investments \(x+y\)
- 14: \(B(x,y)=b_0 (1-\exp(-b_1\ (x+y)))\)
- \(\exp\)-saturating benefits for joint investments \(x+y\)
- 20: \(B(x,y)=b_0 x+b_1\ y+b_2\ x\ y\)
- benefits linear in investments \(x\) and \(y\) as well as cross term \(x\,y\).
- 30: \(B(x,y)=b_0 x\)
- benefits linear in own investments \(x\).
- 31: \(B(x,y)=b_0 x+b_1\ x^2\)
- benefits quadratic in own investments \(x\).
- 32: \(B(x,y)=b_0 x+b_1\ x^2+b_2\ x^3\)
- benefits cubic in own investments \(x\).
