WebbLinear Optimization Methods. For linear objective functions, the simplex method is most commonly used. Although its worst-case behavior is not satisfactory, it works very well for most real-world problems. The mathematical formulation of the problem is to maximize wTv, subject to Av ≤ b and v ≥ 0. http://www.phpsimplex.com/en/simplex_method_theory.htm

A device can send the data but cannot receive it or it can receive the data but cannot send the data. This type of transmission mode is not very popular because the communications require the two-way exchange of data.
