Sabrina Ouazzani (LACL)

In this talk, we present infinite time Turing machines (ITTM), from
the original definition of the model to some new infinite time
algorithms.

We will present algorithmic techniques that allow to highlight some
properties of the ITTM-computable ordinals. In particular, we will
study gaps in ordinal computation times, that is to say, ordinal times
at which no infinite time program halts.
