Perhaps you should try some spelling variations:
"advanced computation using nonlinear programing" » "advanced computations using nonlinear programing" (Expand search), "advanced computational using nonlinear programing" (Expand search), "advance computational using nonlinear programing" (Expand search), "advanced computation using nonlinear programming" (Expand search), "advanced computation using linear programing" (Expand search), "advanced computation using linear programming" (Expand search), "advanced computation in nonlinear programing" (Expand search), "advanced composition using nonlinear programing" (Expand search)
"ising model python python programming" » "ising model pythons python programming" (Expand search), "ising model piton python programming" (Expand search), "ising model pitons python programming" (Expand search), "ising modulo python python programming" (Expand search), "ising monty python python programming" (Expand search), "ising tool python 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: "((\"advanced computation using nonlinear programing\") OR (\"ising model python python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computation using nonlinear programing ) OR ( ising model python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation using nonlinear programing") OR ("ising model python python programming"))*.
