Does it matter in practice to compute optimal prefix free code (i.e. Huffman) faster? [closed]

Which practical software would benefit from a technique to compute optimal prefix free codes faster (say, faster than O(sigma log sigma) on sigma input symbols)? When compressing a source of n symbols over al alphabet of size sigma, computing the Huffman code takes time within O(sigma log sigma), while compression and decompression takes time within…

Normalizer. Do I need supportedInterfaceOrClass?

I’m creating a custom normalizer for node entities. I want to restrict the normalizer to normalize nodes only. It seems like there is two ways to do this: protected $supportedInterfaceOrClass = NodeInterface::class; public function supportsNormalization($data, $format = NULL) { return (bool) $data instanceof NodeInterface; } Are there any difference between the two? Do I need…
