Optimality solutions of stochastic linear program
Given the random LP: $K(x,\epsilon) = min_{a=(a_1,a_2)}\ a_1(w) + a_2(w)$ such that
$$\ a_1(w) - a_2(w) = x-\epsilon$$ and $$a_1(w), a_2(w), x\geq 0,$$ where $\epsilon\sim U(0,1)$ and $w$ is the ...

Stochastic optimization vs stochastic programming
How should I think about the differences between stochastic optimization (SO) and stochastic programming (SP)? From Wikipedia, it seems that SO is a framework that uses randomness to solve a pre-...

Why is it valid to derive a stochastic Euler equation?
Suppose we are given a stochastic dynamic programming problem.
$$\max E\sum_{t=0}^T F(t,X_t, X_{t+1}(X_t,V_{t}),V_{t})$$
Where $V_t$ is a random variable, correlated possibly with $V_{t-1}$. In this ...

Binary Stochastic Programming with Independent or Positively Correlated Co-efficients
A manufacturer can select a maximum of $N$ stores to fulfill orders
from a total of $M$ stores who are looking for inventory, $N\le M$.
The case when $N\geq M$ is trivially solved when all stores ...
