InputIsSmooth

Description

The option InputIsSmooth is only used by the commands CSM, and Euler. If the input ideal is known to define a smooth subscheme setting this option to true will speed up computations (it is set to false by defualt).

R = ZZ/32749[x_0..x_4];
I=ideal(random(2,R),random(2,R),random(1,R));
time CSM I
time CSM(I,InputIsSmooth=>true)

Note that one could, equivalently, use the command Chern instead in this case.
