switches for the simplifier

simp_fold

[default value: 1] A value of 1 causes the simplifier to fold constants when simplifying (e.g., 1+1 --> 2). Any other value prevents the folding of constants.

simp_div

[default value: 1] A value of 1 causes the simplifier to perform symbolic division simplification (e.g., x*y/y --> x). Any other value prevents this.

simp_dist

[default value: 1] A value of 1 causes the simplifier to distribute expressions when simplifying (e.g., (a+1)*(a-1) --> a**2-1). Any other value prevents this simplification.

simp_combine

[default value: 1] A value of 1 causes the simplifier to combine expressions when simplifying (e.g., x+2*x --> 3*x). Other values prevent this simplification.

simp_ratdiv

[default value: 0] A value of 1 causes the simplifier to treat all integer divisions as rational divisions. Other values prevent this simplification.
