Beam search: is a heuristic search algorithm that is an optimization of best-first search that reduces its memory requirement. Beam stack search: integrates backtracking with beam search. Best-first search: traverses a graph in the order of likely importance using a priority queue. Bidirectional search: find the shortest path from an initial vertex to a goal vertex in a directed graph. Bloom filter: a constant time and memory check to see whether a given element exists in a set.
Estimates vary as to how long it took to build the Taj Mahal. Some historians state that it took only 14 years to build it, from 1631-1645, but a more realistic figure is probably 22 years, being completed in 1653.
One of the worldâs most recognisable buildings, the Taj Mahal in Agra, was built between 1632 and 1653 at the behest of Shah Jahan, the fifth Mughal emperor. Shah Jahan was a patron of painting and architecture; the Taj Mahal, a mausoleum devoted to his beloved third wife.
