What is the optimal algorithm for the game 2048? That is why you can not be on the top position by lots of different keywords. Typically, users expect a search query to complete in a short time (such as a few hundred milliseconds for web search), which makes it impossible to evaluate a complex ranking model on each document in the corpus, and so a two-phase scheme is used. For now, we keep things simple. Therefore, it is necessary to develop techniques to evaluate and compare those methods. It is the basis of the ranking algorithm that is used in a search engine to produce the ranked list of documents. According to the client`s requirements, these algorithm should assign a score for each items in data base and retrieve items with highest scores. Once you have designed your algorithm, you can then start to think about your implementation. Normalized discounted cumulative gain is one of the standard method of evaluating ranking algorithms. First, to improve with search engine ranking, follow algorithm guidelines, and tweaks. We also use machine learning to continually evaluate what matters most to guests.
