Perhaps you should try some spelling variations:
"advanced imputation in computer program" » "advanced computations in computer program" (Expand search), "advanced simulation in computer program" (Expand search), "advanced computational in computer program" (Expand search), "advanced mutation in computer program" (Expand search), "advanced imputation of computer program" (Expand search), "advanced implantation in computer program" (Expand search), "advanced imputation _ computer program" (Expand search)
"and computational grids computing program" » "and computational and computing program" (Expand search), "and computational design computing program" (Expand search), "_ computational grids computing program" (Expand search), "and computational grids consulting program" (Expand search), "and computational grids computador program" (Expand search), "and computational grids computer programs" (Expand search), "and computational grid computing program" (Expand search), "and computational green computing program" (Expand search), "and computational grids computer 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: "((\"advanced imputation in computer program\") OR (\"and computational grids computing program\"))~".
• Removing quotes may allow a broader search: (( advanced imputation in computer program ) OR ( and computational grids computing program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced imputation in computer program") OR ("and computational grids computing program"))*.
