Is this what passes for intelligent discourse at Phys.org? So many errors, so little time. First, an algorithm is NOT involved when I pick a movie to stream on Netflix. I pick the movie, Netflix streams it. Unless you want to count the code necessary to display a web page and process a click. Second, algorithms are NOT "complex mathematical formulas." A formula is a specification for a single computational step (or a series of similar steps, in the case of calculus). An algorithm is a non-mathematical procedure, with memory, decision making, input and output from and to various sources and sinks, and, well, formulas. Algorithms contain formulas, but formulas don't contain algorithms.
And phys.org does not contain the sense God gave raisins.
