Abstract: This paper presents event-triggered integral re-inforcement learning methods to solve nonlinear nonzero-sum differential game problems. Firstly, for nonlinear systems, by constructing ...

Abstract: We describe a family of recursive methods for the synthesis of qubit permutations on quantum computers with limited qubit connectivity. Two objectives are of importance: circuit size and ...

Here is the new description with all the links and additional text removed: Learn how to solve equations using the angles sum and difference identities. Using the angles sum and difference identities, ...

I make short, to-the-point online math tutorials. I struggled with math growing up and have been able to use those experiences to help students improve in math through practical applications and tips.

# Given an array of positive integers arr, return the sum of all possible odd-length subarrays of arr. # A subarray is a contiguous subsequence of the array.
