... The evolution of a binary system is considered as a sequence of stages the duration of which are defined by the shortest evolutionary time-scale of one of the binary components (see the list of the evolutionary states of stars in Sections 3 and 4). ... Then the code finds a new stage the binary should transit to, with this stage being determined by the evolutionary states of both components, and calculates it. ... However, one can use the algorithm described above to model their evolution. ...
