Hi experts<br><br><br>I have been working about a C++ implementation of a Branch and Bound algorithm over SDP problems. I have used CSDP in my application by means of CSDP C library. Now, I would like to change some default parameters values, but the easy sdp function does not allow me make that. Can someone say me how I can set the CSDP parameters form C library or where I can get that information? <br>
<br>Best Regards<br><font color="#888888"><br></font></blockquote><div><br>There are two approaches that I can suggest:<br> <br>1. If you want to use the same parameters every time that you call easysdp(), then you can simply create a file called "param.csdp" and set the parameters in param.csdp. The routine that initializes that parameters will take the parameter values from that file. <br>
<br>2. If you want to dynamically adjust the parameters for different subproblems in your branch and bound code, then you'll have to dive a bit deeper into the code and use the sdp() routine instead of easysdp(). <br>
</div></div><br>Please let me know if you have questions about either of these approaches. <br clear="all"><br>-- <br>Brian Borchers <a href="mailto:borchers@nmt.edu" target="_blank">borchers@nmt.edu</a><br>
