  There are only a few Algols with measured accretion disk parameters. These
measurements provide additional constraints for tracing the origin of
individual systems, narrowing down the initial parameter space. We investigate
the origin and evolution of 6 Algol systems with accretion disks to find the
initial parameters and evolutionary constraints for them. With a modified
binary evolution code, series of close binary evolution are calculated to
obtain the best match for observed individual systems. Initial parameters for 6
Algol systems with accretion disks were determined matching both the present
system parameters and the observed disk characteristics. When RLOF starts
during core hydrogen burning of the donor, the disk lifetime was found to be
short. The disk luminosity is comparable to the luminosity of the gainer during
a large fraction of the disk lifetime.
