Hi list, I have two question relating to the Rsymphony package:
a) is there a way to use 'warm starts' ? i.e. if i successively call Rsymphony_solve_LP() with only one constraints change, does it perform the optimization from the simplex-origin or does it uses the previously found solution [i.e. as is common usage, see for instance lpsolveAPI] b) to what extend are sparse matrix supported ? i.e. if a constraint matrix is set as cbind(1,x,diag(dim(x)[1]),-diag(dim(x)[1])) is it understood as sparse ?
