A number of algorithms in silicon valley engineering friends and we share their daily, engineering as an algorithm, develop algorithms time effectively is actually very few, a lot of time spent looking for data, data copy, data cleaning, data conversion, visual script writing, install the framework (tensorflow pytorch) dependence, and mark the team on demand and so on, to do these things may take a week for 10 hours of time, even as high as 95%, if you are an adult algorithm, how do you allocate your time? Every work will spend how much time per week? The percentage of the work or occupy your time?
