Struct smoothed_online_convex_optimization::problem::Online

pub struct Online<P> {
    pub p: P,
    pub w: i32,
}

Online instance of a problem.

Fields

p: P

Problem.

w: i32

Finite, non-negative prediction window.

This prediction window is included in the time bound of the problem instance, i.e. at time $t$ $t_end$ should be set to $t + w$.
