Dijkstra is one of the most popular algorithms in the field of computer science. Known also as a greedy algorithm, it is basically meant to find the shortest path from a starting node to all other nodes in a weighted graph. This vital logic was first conceived by E.W. Dijkstra in 1956.
The downed drone: A US military surveillance drone has been shot down by Iranian forces while flying over the Strait of Hormuz.
Irans Islamic Revolution Guards Corps (IRGC) said the aircraft had violated Iranian airspace, and that the incident sent a "clear message to America".
But the US military insisted the drone had been over international waters at the time, and condemned what it called an "unprovoked attack" by the IRGC.
Here is a little information about the massive drone:The Northrop Grumman RQ-4 Global Hawk is an unmanned (UAV) surveillance aircraft. It was initially designed by Ryan Aeronautical (now part of Northrop Grumman), and known as Tier II+ during development. The Global Hawk performs duties similar to that of the Lockheed U-2. The RQ-4 provides a broad overview and systematic surveillance using high-resolution synthetic aperture radar (SAR) and long-range electro-optical/infrared (EO/IR) sensors with long loiter times over target areas. It can survey as much as 40,000 square miles (100,000 km2) of terrain a day, an area the size of South Korea or Iceland.
Role:Surveillance UAVNational origin:United StatesManufacturer:Northrop GrummanFirst flight:28 February 1998Status:In servicePrimary users:United States Air Force, NASA, NATOProduced: 1998–presentProgram cost:US$10 billion (USAF cost through FY2014)
Northrop Grumman MQ-4C TritonThe Global Hawk is operated by the United States Air Force (USAF). It is used as a High-Altitude Long Endurance platform covering the spectrum of intelligence collection capability to support forces in worldwide military operations. According to the USAF, the superior surveillance capabilities of the aircraft allow more precise weapons targeting and better protection of friendly forces. Cost overruns led to the original plan to acquire 63 aircraft being cut to 45, and to a 2013 proposal to mothball the 21 Block 30 signals intelligence variants.Each aircraft was to cost US$60.9 million in 2001, but this had risen to $222.7 million per aircraft (including development costs) by 2013. The U.S. Navy has developed the Global Hawk into the MQ-4C Triton maritime surveillance platform.
