Bias and No Free Lunch in Formal Measures of Intelligence

Bias and No Free Lunch in Formal Measures of Intelligence

This paper shows that a constraint on universal Turing machines is necessary for Legg's and Hutter's formal measure of intelligence to be unbiased. Their measure, defined in terms of Turing machines, is adapted to finite state machines. A No Free Lunch result is proved for the finite version of the measure.
