Tiivistelmä
We also study the parallel complexity of the decomposition of 2-structures. It is shown that there is a LOGCF algorithm, which recognizes the uniformly nonprimitive 2-structures and constructs their shapes. We prove also that for every MSO (monadic second-order) definable property of 2-structures, there is a LOGCF algorithm to decide whether or not a uniformly nonprimitive 2-structure has that property.
