QUES: Later, von Neumann suggested a new method of linear programming, using the homogeneous linear system of Gordan (1873), which was later popularized by Karmarkar's algorithm. Von Neumann's method used a pivoting algorithm between simplices, with the pivoting decision determined by a nonnegative least squares subproblem with a convexity constraint (projecting the zero-vector onto the convex hull of the active simplex). Von Neumann's algorithm was the first interior point method of linear programming.

What did von Neuman's method use?

QUES: The main local and regional bus station of Utrecht is located adjacent to Utrecht Centraal railway station, at the East and West entrances. Due to large scale renovation and construction works at the railway station, the station's bus stops are changing frequently. As a general rule, westbound buses depart from the bus station on the west entrance, other buses from the east side station. Local buses in Utrecht are operated by Qbuzz – its services include a high-frequency service to the Uithof university district. The local bus fleet is one of Europe's cleanest, using only buses compliant with the Euro-VI standard as well as electric buses for inner city transport. Regional buses from the city are operated by Arriva and Connexxion.
