Estimate the least c so that |C_k(1 / P((1-mx)/x))| < m^(c·k).
Assumption: Ck is the coefficient of xk in the power series of
1 / P((1-mx)/x) around x = 0. We approximate the least c by testing random integer polynomials.
Coefficient bounds are interpreted as multiples of m: aᵢ ∈ [coeffMin·m, coeffMax·m]. You can
type a number (e.g. 0.5) or a factor like m, -m, 2m.
