Unbalanced urn model with random addition
Rafik Aguech, Nabil Lasmar, Olfa Selmi
In this paper, we consider a multi-drawing urn model with random addition. At each discrete time step, we draw a sample of m balls. According to the composition of the drawn colors…

Multiple drawing multi-colour urns by stochastic approximation
Nabil Lasmar, Cécile Mailler, Olfa Selmi
A classical Pólya urn scheme is a Markov process whose evolution is encoded by a replacement matrix . At every discrete time-step, we draw a ball unifo…
