[Help-glpk] Addding an extra constraint to the problem-more calrification

[Shubhashis Ghosh]

Hi,

  Further clarification of my previous question.

 I was working with problem lp (m constraints, n variables). Suppose at 
certain stage of primal simplex method I have a simplex tableau representing 
a feasible solution x* of the problem. Now I want to add 
one more constraint ax>=b which is satisfied by x*. The new problem 
lp' will have (m+1 constraints, n variables). At the end I want to have 
a simplex tableau which has the same feasible solution x* (basis will 
contain the previoius basic variables and the new slack veriables). 

>From now on I want to work with lp' from that basis removing the problem 
lp. 

Can anyone tell me how it can be done quickly 
using some glpk callable routine? 


thanks,
