< p > To approximate a payout curve that is not a piecewise polynomial function, one may either propose a new kind of curve to the specification, or use approximation. For example by feeding < code > DLCPayoutCurve< / code > a list of < code > PiecewisePolynomialEndpoint< / code > s, one receives a linear approximation of their payout curve which takes the sampled points and " connects the dots" with straight lines. Alternatively one can use spline interpolation and sample two midpoints of every spline to get a piecewise cubic interpolation.< / p >
