+        <para>A Simulated Annealing optimization method.</para>
+        <para>
+            Simulated annealing (SA) is a generic probabilistic meta-algorithm for the global optimization
+            problem, namely locating a good approximation to the global optimum of a given function in a
+            large search space. It is often used when the search space is discrete (e.g., all tours that
+            visit a given set of cities).
+        </para>
+        <para>
+            The current solver can find the solution of an optimization problem without constraints or 
+            with bound constraints. The bound constraints can be customized with the neighbour
+            function. This algorithm does not use the derivatives of the objective function.
+        </para>
+        <para>
+            The solver is made of Scilab macros, which enables a high-level programming model for
+            this optimization solver. The SA macros are based on the <literal>parameters</literal>
+            Scilab module for the management of the (many) optional parameters.
+        </para>
+        <para>
+            To use the SA algorithm, one should perform the following steps :
+            <itemizedlist><listitem>
+                    configure the parameters with calls to <literal>init_param</literal> 
+                    and <literal>add_param</literal> especially the neighbor function, the 
+                    acceptance function, the temperature law,

+            </itemizedlist>
+        </para>
+        <para>
+            The algorithm is based on an iterative update of two points :
+            <itemizedlist><listitem>
+                    the current point is updated by taking into account the neighbour and the acceptance
+                    functions,
+                </listitem>
+                <listitem>
+                    the best point is the point which achieved the minimum of the objective function over the
+                    iterations.
+                </listitem>
+            </itemizedlist>
+            While the current point is used internally to explore the domain, only the best point is returned
+            by the function.
+            The algorithm is based on an external loop and an internal loop. In the external loop,
+            the temperature is updated according to the temperature function. In the internal loop, the 
+            point is updated according to the neighbour function. A new point is accepted depending 
+            on its associated function value or the value of the acceptance function, which value 
+            depends on the current temperature and a uniform random number.
+        </para>
+        <para>
+            The acceptance of the new point depends on the output values produced
+            by the <literal>rand</literal> function. This implies that two consecutive 
+            calls to the <literal>optim_sa</literal> will not produce the same result.
+            In order to always get exactly the same results, please initialize the random number 
+            generator with a valid seed.
