python - When should you use ax. in matplotlib? -


i still don't understand best usage of fig, plt. , ax. in matplotlib should using plt. time? when should ax. used?

use fig , ax part of object oriented interface , should used possible.

using old plt interface works in cases too, when create , manipulate many figures or axes can become quite tricky keep track of figures:

plt.figure() plt.plot(...)      # implicitly modifies axis created beforehand plt.xlim([0, 10])  # implicitly modifies axis created beforehand plt.show()

compared 

fig, ax = plt.subplots(1, 1) ax.plot(...)           # explicitly modifies axis created beforehand ax.set_xlim([0, 10])   # explicitly modifies axis created beforehand plt.show()

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
