Crowdsourcing involves incentives, and hence, costs, such as monetary costs for pay- ments for answers as well as efficiency costs, e.g., in terms of time taken to achieve an adequate response. Algorithms where humans are viewed as data processors have been explored for finding the maximum...
Also we shall refer to the local minima of the effective potential as its vacua, and label the global minimum as the true vacuum, while all the others are false vacua. A potential may have multiple true vacua, either as a continuous set of minima related by gauge transformations as in the...
Finding the optimal/best rotation and translation between two sets of corresponding 3D point data, so that they are aligned/registered, is a common problem I come across. An illustration of the problem is shown below for the simplest case of 3 corresponding points (the minimum required points ...
