+///different inputs, running methods, etc. Therefore
+///class \ref AlgoWin is only a holder of a base class, the so
+///called AlgoBox. \ref AlgoBox is the ancestor of other
+///classes. These child classes realize interfaces of different
+///algorithms, but as their common ancestor is \ref AlgoBox
+///the interface of them is the same. \ref AlgoWin communicates
+///with these classes through this common interface. But it the
+///real object to be placed in \ref AlgoWin depends on the algorithm
+///which the \ref AlgoWin actually has to display. It gets the
+///id of algorithm to display at initialization, and therefore it is
+///able to place in itself the requested child of \ref AlgoBox
+/// visualizing the appropriate algorithm.
