getVariableOverridesCount

public int getVariableOverridesCount()

Description copied from interface: MPModelDeltaProtoOrBuilder

 The variable protos listed here will override (via MergeFrom()) the ones
 in the baseline model: you only need to specify the fields that change.
 To add a new variable, add it with a new variable index (variable indices
 still need to span a dense integer interval).
 You can't "delete" a variable but you can "neutralize" it by fixing its
 value, setting its objective coefficient to zero, and by nullifying all
 the terms involving it in the constraints.

getConstraintOverridesCount

Description copied from interface: MPModelDeltaProtoOrBuilder

 Constraints can be changed (or added) in the same way as variables, see
 above. It's mostly like applying MergeFrom(), except that:
 - the "var_index" and "coefficient" fields will be overridden like a map:
 if a key pre-exists, we overwrite its value, otherwise we add it.
 - if you set the lower bound to -inf and the upper bound to +inf, thus
 effectively neutralizing the constraint, the solver will implicitly
 remove all of the constraint's terms.
