Understanding MDP's Dual Linear Program
I'm trying to understand a proof in Puterman'05 (Markov Decision Processes: Discrete Stochastic Systems). My question is within Theorem 6.9.1 pertaining to the equivalence of solutions to the primal (...

MDP model for a unique system
Let's assume that we have a system where there are two exogenous factors, name $a$ and $b$, that can affect the system state. At each decision epoch either $a$ or $b$ occurs and it is not possible ...

Markov Chain - Stationary or Borderline distribution [closed]
I have a Markov chain problem below, where :
The problem
An urn initially contains 3 black balls and 1 red ball. The balls are indistinguishable to the touch. One ball is randomly drawn.
If this ball ...

Equilibria in two player, finite horizon, zero sum stochastic game
Suppose we have a two player, finite horizon, zero sum stochastic game (a.k.a. "competitive MDP"). The game is defined over a finite set of state $S$. At each decision epoch $t\in\{1,\dots,T\}$ (for ...

Queuing Theoretic Model with Memory
Consider a telephone company which receives call request at some arrival rate and serves each request with some service rate. This can be modeled using a Poisson Process. However I wish to model the ...

Can I use an MDP for a stochastic inventory model when my demand distribution is non-stationary?
Most formulations of Markov Decision Processes for stochastic inventory models I've come across assume a fixed demand distribution.
But in my case I have a time series forecast with a non stationary ...

Number of aircraft to operate in an airline company
Suppose that an airline company has X planes, in general the companies keep a number of these aircraft (say 80% of X) in reserve in case of hazards. My question is how the airline companies compute ...

For the solution of complex gaming are we to leave behind approximation and fixed algorithms in favor of agents?
For an evolutionary extensive form game is the use of multi-agent systems a necessity or can more traditional approximate Nash equilibria and mean-field interactions suffice?
Few games can be ...

Open source Markov decision process solvers
Which sources are out there that provide reliable and fast MDP solvers? I prefer that the library is callable from C++ but other languages are fine too.
There is indeed an abundance of repositories ...

Convergence rate value iteration
Value iteration is one of the most commonly used methods to solve Markov decision processes. Its convergence rate obviously depends on the number of states and actions. However, the convergence rate ...
