The Monte Carlo searching method (Abdallah I. Husein
2001) has two shortcomings
one is that its result has random characteristic
the other is that it is inclined to fall into the local extremum in complex condition. This paper extends the method by transferring random angle of rotation to constant angle of rotation
which makes it determinate method. Several examples show that extended method (EMC) has both the characteristics of random walking and random jumping
so that it is higher precious and more effective; and moreover EMC can work properly whether or not the initial slip surface is convergence solving safety factor. Although the rotation angle has a little influence on results by EMC
in practical engineering only several angles need to be tried to obtain reasonable results; unless slope mass has slightness weak layers
when more tries of different angles or several various initial slip surfaces are needed.
