Stable belt Stable belt A stable belt is an item of uniform used in the armed forces of Denmark, the United Kingdom and other Commonwealth countries. Gymnastic belts are similar coloured belts used in Brazil and Lebanon. The stable belt originates from when cavalrymen would place the surcingle around the waist when cleaning the stables and tending to their horses. In the 1950s they spread to all branches of the armed forces, adding a splash of colour and individuality to the drab khaki working uniforms. Initially they were resisted by many senior officers, who saw them as too individualistic, but they soon
Matroid girth oracle, it is impossible to find the girth using a subexponential number of matroid queries. Similarly, for a real linear matroid of rank , with elements, described by an oracle that gives the orientation of any -tuple of elements, it requires formula_1 oracle queries to determine the girth. Computations using a girth oracle (an oracle that reports the smallest dependent subset of a given set of elements) have also been considered. Matroid girth In matroid theory, a mathematical discipline, the girth of a matroid is the size of its smallest circuit or dependent set. The cogirth of a matroid is
