This paper proposes a novel condition-based algorithm for the uniform
consensus in synchronous systems. The proposed algorithm is
{\em adaptive} in the sense that its execution time depends on
actual difficulty of input vectors, {\em legality level}, which
is newly formalized in this paper. On the assumption that
majority of processes are correct, the algorithm terminates
within $\min\{f + 2 - l, t + 1\}$ rounds if $l < f$, where
$f$ and $t$ is the actual and the maximum numbers of faults
respectively,
and $l$ is the legality level of input vectors. Moreover, the
algorithm
terminates in $1$ round if $l \geq t$ and $f=0$, and terminates
within $2$ rounds if $l \geq f$ holds.
Compared with previous algorithms, for the case of $t < n/2$,
the algorithm achieves the best time complexity in almost all situations. |
