+We use the following variables in our algorithms and models :
 
+\begin{itemize}
+
+	\item $ U_n $ : the size of the $ n $-th item. $ (U_n)_{n \in \mathbb{N}} $
+	      denotes the mathematical sequence of random variables of uniform

+
+	\item $ T_i $ : the number of items in the $ i $-th bin.

+
+	\item $ H_n $ : the number of bins required to store $ n $ items.
