I just started Python and I've got no idea what memoization is and how to use it. Also, may I have a simplified example?

When looking up memoization in Haskell, I found this bit of code: memoized_fib :: Int -> Integer memoized_fib = (map fib [0 ..] !!) where fib 0 = 0 fib 1 = 1 fib n = ...

What is the difference between memoization and dynamic programming? I think dynamic programming is a subset of memoization. Is it right?

I have a mathematical function called in render loop (240Hz). It's a function of some (atomic) state that very rarely changes. It calls 3 times to std::log, twice to std::sqrt, once to std::sin. When ...

Consider the following: @property def name(self): if not hasattr(self, '_name'): # expensive calculation self._name = 1 + 1 return self._name I'm new, but I think the ...

I have a set of integers. I want to find the longest increasing subsequence of that set using dynamic programming.

The bottom-up approach (to dynamic programming) consists in first looking at the "smaller" subproblems, and then solve the larger subproblems using the solution to the smaller problems. The top-down ...

I'm writing a class in python and I have an attribute that will take a relatively long time to compute, so I only want to do it once. Also, it will not be needed by every instance of the class, so I ...

Is there a way to memoize the output of a function to disk? I have a function def getHtmlOfUrl(url): ... # expensive computation and would like to do something like: def getHtmlMemoized(url) = ...

I have a simple scenario in which I want to access my store.entities, but only those which are active. I understand the following is bad because a new reference is given each time: const ...

I have an app with cards. Cards are fetched with useInfiniteQuery from React Query. I fetch new card each time I reach the end of the list. Backend sends offset and limit based responses of this ...

Problem: Given an array that sums to 0, find the maximum number of partitions of it such that all of them sum up to 0 individually. Example: input: [-2, 4, -3, 5, -4] output: 2 (which are [[5, -2, -3]...

Just by using the commented code instead of making the recursive calls inside the max function, leads to incorrect result particularly with the following test case int main() { Solution obj = ...

How can the following recursion + memoization code be converted into a tabulation format dynamic programming solution? The code is working but I want to improve it. The challenge I am facing is ...

Any pointers on how to solve efficiently the following function in Haskell, for large numbers (n > 108) f(n) = max(n, f(n/2) + f(n/3) + f(n/4)) I've seen examples of memoization in Haskell to ...
