They can be useful in the cases when graphs are so large that it takes a lot of time and energy to process, even just iterating through the whole graph and the associated computation is heavy. This seems almost impossible, and while such algorithms cannot give exact answers, in many real cases approximate results are enough.\u003C\/p\u003E\r\n\r\n\u003Cp\u003ELast winter break,\u0026nbsp;I wrote a basic review system on top of the\u0026nbsp;\u003Ca href=\u0022https:\/\/www.ethereum.org\/\u0022\u003EEthereum\u003C\/a\u003E\u0026nbsp;blockchain system.
