| 12 | The result of <b class="userinput"><tt>make unitTest</tt></b> (executed in |
|---|
| 13 | <tt class="filename">COIN/Clp</tt>) is an executable |
|---|
| 14 | <tt class="filename">clp</tt> as well as the CLP and COIN libraries. |
|---|
| 15 | The executable can be used to perform various unit tests, but can also be used |
|---|
| 16 | as a standalone solver. As the executable has a very simple solution file format, |
|---|
| 17 | the user may wish to modify <tt class="filename">COIN/Clp/Test/ClpMain.cpp</tt>, |
|---|
| 18 | which contains the source of the executable (modifications could even be |
|---|
| 19 | offered as a contribution to CLP). |
|---|
| 20 | </p><p> |
|---|
| 21 | The <tt class="filename">clp</tt> executable operates in command line mode or |
|---|
| 22 | prompted mode. Entering <b class="userinput"><tt>clp</tt></b> will invoke the prompted |
|---|
| 23 | mode, while <b class="userinput"><tt>clp <filename></tt></b> will import a problem |
|---|
| 24 | in MPS format from <tt class="filename">filename</tt>, solve it using the dual |
|---|
| 25 | simplex method and exit. The command |
|---|
| 26 | <b class="userinput"><tt>clp <filename> -primalsimplex</tt></b> instructs the |
|---|
| 27 | executable tp import a file and solve using the primal simplex method. An |
|---|
| 28 | additional solitary dash ("<b class="userinput"><tt>-</tt></b>") starts the |
|---|
| 29 | prompt mode once the execution of the initial command has been completed. The |
|---|
| 30 | "<b class="userinput"><tt>-</tt></b>" is necessary as part of the command; |
|---|
| 31 | invoking prompt mode as a separate command will result in the loss of problem |
|---|
| 32 | information related to the initial command. So, the following sequences of commands |
|---|
| 33 | are equivalent in the sense that both maximize a problem using the dual |
|---|
| 34 | simplex method and write a solution to file: |

| 35 | <tt class="filename">solfile</tt>: |
