FuncPieceRatio
Control whether to under- or over-estimate function values in PWL approximation
| Type: | double | |
|---|---|---|
| Default value: | -1 | |
| Minimum value: | -1 | |
| Maximum value: | 1 |
This parameter controls whether the piecewise-linear approximation of
a function constraint is an underestimate of the function, an
overestimate, or somewhere in between. A value of 
will always
underestimate, while a value of 
will always overestimate. A
value in between will interpolate between the underestimate and the
overestimate. A special value of -1 chooses points that are on the
original function.
The behaviour is not defined for other negative values.
See the discussion of function constraints for more information.
