Replacing LET formulas with helper columns made my Excel workbooks easier to audit, adapt, and troubleshoot.
Switch statements let you streamline multi-condition logic in programming and even spreadsheets. By matching a single expression against multiple cases, they cut down repetitive code. Whether in ...
In the past two columns, we’ve looked at higher-order functions and talked a little bit about the power of functional programming. So far, the concepts we’ve covered do little to indicate how powerful ...
‘Higher-order functions’ is a fancy term for functions that take other functions as arguments or that return functions. Very powerful! Last week, I casually dropped the term “higher-order function” ...
In this paper, a new augmented Lagrangian penalty function for constrained optimization problems is studied. The dual properties of the augmented Lagrangian objective penalty function for constrained ...
