The transpiler pass :class:`.LookaheadSwap` (used by :func:`.transpile` when
|
|
``routing_method="lookahead"``) has seen some performance improvements and
|
|
will now be approximately three times as fast. This is purely being more
|
|
efficient in its calculations, and does not change the complexity of the
|
|
algorithm. In most cases, a more modern routing algorithm like
|
|
:class:`.SabreSwap` (``routing_method="sabre"``) will be vastly more
|
|
performant.
