Optimal Spread (2)

Is turns out we also have to distribute x(t)’s such that we follow a non-uniform parameter. In the previous section http://yetanothermathprogrammingconsultant.blogspot.com/2011/05/optimal-spread.html we used a function v(t) = 1 with cumulative function w(t) = t.

In this case we consider a generic parameter v(t), with its cumulative cousin w(t)=w(t-1)+v(t). To trace this function as closely as possible we can use:

spread6

E.g. when we use v(t)=t, then we see:
