Quay crane efficiency is the key bottleneck for container port productivity. An important issue of container terminal optimization is the quay crane double-cycling problem (QCDCP). For the simple ...

A new algorithm generates practical paper-folding patterns to produce any 3-D structure. In a 1999 paper, Erik Demaine -- now an MIT professor of electrical engineering and computer science, but then ...

In the (deletion-channel) trace reconstruction problem, there is an unknown n-bit source string x. An algorithm is given access to independent traces of x, where a trace is formed by deleting each bit ...
