SCALINGOPS

Description
This bit-vector control (see Section Bit-vector controls) is allows finer-grained control of the scaling process. In most circumstances it should not be necessary to change it from it's default value.
Type
Integer
Topic areas
Numerics, Problem Transformation, Bit-vector
Values
Bit
Meaning
0 
Row scaling.
1 
Column scaling.
2 
Row scaling again.
8 
Exclude the quadratic part of constraint when calculating scaling factors.
10 
Do not scale rows up.
11 
Do not scale columns down.
12 
Do not apply automatic objective scaling.
13 
RHS scaling.
14 
Disable aggressive quadratic scaling.
15 
Enable explicit linear slack scaling.
Default value
3, meaning bits 0 and 1 are set
Affects routines
XPRSlpoptimize, XPRSmipoptimize, XPRSscale ( SCALE).
