The advanced adjoint approach for arbitrary collisionalities with momentum conservation in the like-particle collision is considered. The results are generally applicable for the parallel conductivity as well as for current drive calculations. In addition, the weakly relativistic extension of the variational principle for the Spitzer function with momentum conservation in the electron-electron collision is described. The models developed are well suited to ray-tracing calculations.
