Note that we cannot address the issue of changing level values within the same basis in the GAMS model, since the GAMS model itself does not store the current basis matrix. | Note that we cannot address the issue of changing level values within the same basis in the GAMS model, since the GAMS model itself does not store the current basis matrix. | ||

- | To determine the range of values a particular parameter can take without forcing a change in the current basis, but while allowing the level values to change, one must have a representation of the current basis. Since GAMS does not keep this information, these ranges must be produced by the LP solver. Documentation on how this is done using GAMS/CPLEX is given [[solver:sensitivity_analysis_with_gams_cplex|here]] | + | To determine the range of values a particular parameter can take without forcing a change in the current basis, but while allowing the level values to change, one must have a representation of the current basis.
