Educational data mining methods often differ from methods from the broader data mining literature, in explicitly exploiting the multiple levels of meaningful hierarchy in educational data. Methods from the psychometrics literature are often integrated with methods from the machine learning and data mining literatures to achieve this goal.

Economics. At the time of writing, the reward is 12.5 bitcoins, which at time of writing is worth almost $200,000. Although it's not nearly as cushy a deal as it sounds. There are a lot of mining nodes competing for that reward, and it is a question of luck and computing power (the more guessing calculations you can perform,

Four main methods of mining are available underground, open surface (pit), placer and in-situ mining. Underground mines are more expensive and often used to reach deposits that are deeper. Surface mines are usually used for deposits that are shallower and less valuable.

Underground mining accounts for 60% of world coal production, but is less common in NSW, making up around 35% of raw coal production. This method is also used to mine metallic minerals like gold and copper. The two main types of underground mining in NSW are bord-and-pillar and longwall mining.

In each of these mining methods, various earth-moving equipment including shovels, dozers, hauling trucks, and loaders are used to remove and transport the ore. However, the first step is to loosen the rock in the ore body so that it can be moved and processed. Blasting and grinding equipment are used to accomplish this task.

Both are vulnerable to intervention by a third party (ie drones or hostile players) but could have counters such as weapons to defend themselves. A mining platform would be quicker, but also more expensive and requires manual assembly and disassembly.
