Figure 6.4: 2D Chooser. Sparse vs. full solution. Slices.<br />
The Figure (6.4) above shows how Level 6 <strong>sparse</strong>-<strong>grid</strong> approximated solution corresponds to<br />
<strong>the</strong> full <strong>grid</strong> counterpart as we freeze one of <strong>the</strong> forward rates.<br />
