From: Honesty in signalling games is maintained by trade-offs rather than costs
Method for reverse-engineering the general trade-off function T. The method transforms any (at least twice) differentiable signaller benefit function B to the fitness function wS that has the same optimal amount of shared resource as the receiver’s fitness function wR. For sake of simplicity, function arguments are omitted at the right side of equations. D and higher order Taylor coefficients τ3, τ4, … can be freely chosen
