A method for making high purity dicyclopentadiene comprises the following steps: providing a dimer feedstock comprising dicyclopentadiene and methyl dicyclopentadiene; blending the dimer feedstock and a diluent to obtain a first blend; cracking the first blend in a vapor phase at 300\xb0 C. A multisolver matrix that represents the collective effect of movements of each edge segment in the mask layout is used to simultaneously determine the correction amount for each edge segment in the mask layout.
