Pantelides algorithm
 | This article provides insufficient context for those unfamiliar with the subject. (August 2010) |
Pantelides algorithm gives a systematic method for reducing high-index systems of differential-algebraic equations to lower index, by selectively adding differentiated forms of the equations already present in the system[1][2][3]. It is possible for the algorithm to fail in some instances.
Pantelides algorithm is implemented in several significant equation-based simulation programs such as Modelica and EMSO[4][5][6]
