Thanks , but How can set a design for a model that is nonlinear in parameters?

I am assuming that I an expected utility form  between probabilities and payoff.

My attributes here are the probability (p) of an outcome and the outcome itself (X) plus an alternative outcome (Y).

Thus, EU=p*u(X)+(1-p)*u(Y)=p*(u(X)-u(Y))+u(Y)

Further, utility here can be for example u(x)=x^a and further probability p can be distorted in a non-linear function w(p)=p^b.

Hence, I have EU=p^b*(x^a-y^a)+y^a

Is there a way to specify a design in sawtooth for this type of models?

Sawtooth Software's design algorithms are meant to nearly optimize the situation of linear in parameters additive decision rules (plus selected first order interactions).  How efficient they are for your model specification I do not know.
