comment Implementing a For (?) or series or loop (?) for individual results for every x to n
Can't you import the whole spreadsheet (.xls etc.) and manipulate the data in Mathematica session then write them back, rather then read 2 rows each time?

comment How to find local minima of a multivariate function with singularity?
I'm still not exactly sure why converting Indeterminate to $MaxMachineNumber is safe that no $-\infty$ will not be mistakenly converted.

comment How to find local minima of a multivariate function with singularity?
Could you explain a little that why when Sigmoid returns exactly 0 or 1, there will then be a Indeterminate? Is it that y_i - Sigmoid[...] is somehow used as a denominator in the computation?

I know; Do this fact help answer the question? Or do you mean define the symbol by assigning a value? How to create the symbol without having to assign it an arbitrary value at the same time?
