Fundamental questions on chance-constrained problem

Chance-constrained is an optimization problem that ensures, probability of meeting a constraint is above a certain level. The formulation of this problem is generally defined as : $ \min \mathbb E_\...

Understanding two-stage linear stochastic programming problem's formulation

The classical two-stage linear stochastic programming problems, where at the first stage the decision variable is $x$, can be formulated as: $$\min_{x}\{g(x):=c'x+\mathbb{E}[Q(x,\xi)]\},$$ where $Q(x,\...

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 ...

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 ...
