Comment:

 If you enable the option
 {{{
 jacobian_approximation finite-difference-values
 }}}
 (e.g., by placing it into a file named {{{ipopt.opt}}}, then Ipopt will
 still request the sparsity structure of the Jacobian by calling
 {{{FEval_Jac_G_CB}}} with {{{TASK=0}}}. However, there should be no calls
 with {{{TASK=1}}}.
