Perhaps you should try some spelling variations:
"and computation using loading problem" » "and computations using loading problem" (Expand search), "and computation in loading problem" (Expand search), "and composition using loading problem" (Expand search), "and computational using loading problem" (Expand search), "of computation using loading problem" (Expand search), "and computation using routing problem" (Expand search), "and computation using planning problem" (Expand search), "and computation using locking problem" (Expand search), "and computation using shading problem" (Expand search), "and computation using coding problem" (Expand search)
"using model from python programming" » "ising model from python programming" (Expand search), "using modis from python programming" (Expand search), "using mobile from python programming" (Expand search), "using model from pathogen programming" (Expand search), "using model from anthony programming" (Expand search), "using models from python programming" (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: "((\"and computation using loading problem\") OR (\"using model from python programming\"))~".
• Removing quotes may allow a broader search: (( and computation using loading problem ) OR ( using model from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computation using loading problem") OR ("using model from python programming"))*.
