TriangleExp{T, S<:Integer}(range0, range1, period, decay)
TriangleExp(λ0, λ1, period, γ)
TriangleExp(;λ0, λ1, period, γ)

A triangle wave schedule with period and an exponentially decaying amplitude. The output conforms to

abs(λ0 - λ1) * Triangle(t) * γ^(t - 1) + min(λ0, λ1)

where Triangle(t) is (2 / π) * abs(asin(sin(π * (t - 1) / schedule.period))) (see Triangle).

Arguments

• range0/λ0: the first range endpoint
• range1/λ1: the second range endpoint
• period::Integer: the period
• decay/γ: the decay rate
