Input: windowSize, S = , batchSize
Output:  C =
(1)  slideWindow = , apprSet =
(2)  Read data into slideWindow
(3)  While  ReadIn() do
(4)   tmpSet = MDLSlideWindow(slideWindow,
    batchSize);
(5)   If  tmpSet.size() < 2 do
    // no proper hypothesis is found,
    data deemed as random noise
(6)   Add all data in slideWindow into apprSet
(7)   Empty slideWindow
(8)  Else
(9)   Add at most first batchSize + 1 points in
    tmpSet into apprSet
(10)    Take out used points from slideWindow
(11)       Output apprSet
