Problem: 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?
The answer is the following: pivoting algorithm between simplices

Problem: By the early 1970s Portugal's fast economic growth with increasing consumption and purchase of new automobiles set the priority for improvements in transportation. Again in the 1990s, after joining the European Economic Community, the country built many new motorways. Today, the country has a 68,732 km (42,708 mi) road network, of which almost 3,000 km (1,864 mi) are part of system of 44 motorways. Opened in 1944, the first motorway (which linked Lisbon to the National Stadium) was an innovative project that made Portugal among one of the first countries in the world to establish a motorway (this roadway eventually became the Lisbon-Cascais highway, or A5). But, although a few other tracts were created (around 1960 and 1970), it was only after the beginning of the 1980s that large-scale motorway construction was implemented. In 1972, Brisa, the highway concessionaire, was founded to handle the management of many of the regions motorways. On many highways, toll needs to be paid, see Via Verde. Vasco da Gama bridge is the longest bridge in Europe.
After joining the European Economic Community in the 90's, what did Portugal begin building?
The answer is the following: new motorways

Problem: Following Thein Sein's first ever visit to the UK and a meeting with Prime Minister David Cameron, the Myanmar president declared that all of his nation's political prisoners will be released by the end of 2013, in addition to a statement of support for the well-being of the Rohingya Muslim community. In a speech at Chatham House, he revealed that "We [Myanmar government] are reviewing all cases. I guarantee to you that by the end of this year, there will be no prisoners of conscience in Myanmar.", in addition to expressing a desire to strengthen links between the UK and Myanmar's military forces.
What would the official like to see happen between the two countries ?
The answer is the following: a desire to strengthen links between the UK and Myanmar's military forces

Problem: The city had surrendered without a fight to the invading Moors (Berbers and Arabs) by 714 AD, and the cathedral of Saint Vincent was turned into a mosque. Abd al-Rahman I, the first emir of Cordoba, ordered the city destroyed in 755 during his wars against other nobility, but several years later his son, Abdullah, had a form of autonomous rule over the province of Valencia. Among his administrative acts he ordered the building of a luxurious palace, the Russafa, on the outskirts of the city in the neighbourhood of the same name. So far no remains have been found. Also at this time Valencia received the name Medina al-Turab (City of Sand). When Islamic culture settled in, Valencia, then called Balansiyya, prospered from the 10th century, due to a booming trade in paper, silk, leather, ceramics, glass and silver-work. The architectural legacy of this period is abundant in Valencia and can still be appreciated today in the remnants of the old walls, the Baños del Almirante bath house, Portal de Valldigna street and even the Cathedral and the tower, El Micalet (El Miguelete), which was the minaret of the old mosque.
When did Valencia surrender to the Moors?
The answer is the following:
by 714 AD
