Sorting algorithm, in computer science, a procedure for ordering elements in a list by repeating a sequence of steps. Sorting algorithms allow a list of items to be sorted so that the list is more usable than it was, usually by placing the items in numer
A previous study has shown that the complexity of an instance can be quantified as the minimum level of k necessary to achieve optimality with the Sahni-k algorithm4. The parameter k scales with the time and memory requirement. Similar in spirit, we defined another complexity metric based on ...
Computer science - Algorithms, Complexity, Programming: An algorithm is a specific procedure for solving a well-defined computational problem. The development and analysis of algorithms is fundamental to all aspects of computer science: artificial intell
We present an algorithm for reducing the size and complex- ity of the Interaction Network, a data structure used for storing solution paths explored by students in open-ended multi-step problem solving environments. Our method re- duces the number of edges and nodes of an Interaction Net- ...
Amorphous calcium carbonate is an important precursor for biomineralization in marine organisms. Key outstanding problems include understanding the structure of amorphous calcium carbonate and rationalizing its metastability as an amorphous phase. Here we report high-quality atomistic models of amorphous calcium...
We know that this is possible but, in general, this happens only provided that we are lucky enough to initialize the algorithm in the basin of attraction of a global minimum. While there is a huge literature on numerical optimization, one should be very well aware of the very local nature...

And does anyone want an artificial intelligence algorithm to deny claims without any review by real medical professionals? Yet, any push for health care simplification inevitably clashes with commercial interests. The health insurance system is structured to simultaneously maximize profits, control costs,...
