False position method to "regula falsi" is sometimes called the Illinois algorithm. Ford (1995) summarizes and analyzes this and other similar superlinear variants of the method of false position. Put simply: When the new -value (that is, )) has the same sign as the previous one ()), meaning that the end point of the previous step will be retained, the Illinois version halves the -value of the retained end point in the next estimate computation. Suppose that in the -th iteration the bracketing interval is and that the functional value of the new calculated estimate has the same sign as . In this
Midfielder According to positioning along the field, attacking midfield may be divided into "left, right" and "central attacking midfield" roles but mostly important he is a striker behind the forwards. A central attacking midfielder may be referred to as a "playmaker", or "number ten" (due to the association of the number 10 shirt with this position). A good attacking midfielder needs good passing abilities, vision, the ability to make long shots, and solid dribbling skills. These players typically serve as the offensive pivot of the team, and are sometimes said to be "playing in the hole," although this term can also
