BARCRASH

Newton barrier: This determines the type of crash used for the crossover. During the crash procedure, an initial basis is determined which attempts to speed up the crossover. A good choice at this stage will significantly reduce the number of iterations required to crossover to an optimal solution. The possible values increase proportionally to their time-consumption.

Integer

0	Turns off all crash procedures.
1-6	Available strategies with 1 being conservative and 6 being aggressive.
