Perhaps you should try some spelling variations:
"variance optimization _ coding program" » "surface optimization _ coding program" (Expand search), "engine optimization _ coding program" (Expand search), "value optimization _ coding program" (Expand search), "variance optimization _ cloning program" (Expand search), "variance optimization _ loading program" (Expand search), "variance optimization _ cooling programs" (Expand search)
"and factorization using coding program" » "and vectorization using coding program" (Expand search), "and atomization using coding program" (Expand search), "and valorization using coding program" (Expand search), "and authorization using coding program" (Expand search), "lu factorization using coding program" (Expand search), "and factorization using cloning program" (Expand search), "and factorization using loading program" (Expand search), "and factorization using cooling programs" (Expand search), "and factorization using coping program" (Expand search), "and factorization using coating program" (Expand search), "and factorization using cooking program" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"variance optimization _ coding program\") OR (\"and factorization using coding program\"))~".
• Removing quotes may allow a broader search: (( variance optimization _ coding program ) OR ( and factorization using coding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("variance optimization _ coding program") OR ("and factorization using coding program"))*.
