+
+In order to implement efficiently a PRNG based on chaotic iterations it is
+possible to improve previous works [ref]. One solution consists in considering
+that the strategy used $S^i$ contains all the bits for which the negation is
+achieved out. Then instead of applying the negation on these bits we can simply
+apply the xor operator between the current number and the strategy $S^i$.

+In Figure~\ref{algo:seqCIprng} a sequential version of our chaotic iterations based PRNG is
+presented. This version uses three classical 64-bits PRNG: the xorshift, the
+xor128 and the xorwow. These three PRNGs are presented in~\cite{Marsaglia2003}.
