Panda, Penguin, Hummingbird were some of the algorithm that Google launched to address specific issues. The Panda algorithm update started in Feb 2011, saw over 25 updates to the codes and spanned over 2 years where it was constantly enhanced to address any bugs.
In late September 2013, Google announced that they launched the Hummingbird codes to humanize and break down long term search queries. The key concept that they focused on addressing is to serve relevant content based on “User Intent”.
The traditional algorithm will weight the user query evenly, such as “Where is the best place to buy Microsoft Surface tablet?”, where all the words are weighted. The Hummingbird algorithm will take input from the user such as the user’s previous search preference, proximity to a store that sells the product, prices of the device, and appending social listening to the search engine results page (SERPs). Google will not disclose other things that the Hummingbird is set out to address.
