Game Theory | Fibonacci Game
Fibonacci Game Game theory is a theory in which two or more people use each other’s strategies to change their own confrontation strategies in an equal game to achieve the goal of winning. Game theory is the study of interactive decision-making. Games can analyze the pros and cons between oneself and the opponent, thereby establishing […]
Revisiting time complexity from the Fibonacci sequence
Introduction to Fibonacci Code Demonstration: Recursion, Loop recursion vs loop The time is complex and complex, exponential O(2^n); derivation process Occupies the thread stack, which may cause a stack full exception Visual demonstration of pressure measurement When entering into software development, the Fibonacci sequence is a simple programming algorithm that cannot be bypassed. A common […]
Dynamic programming Fibonacci sequence model
Fibonacci sequence model 1. The Nth Taibonacci number 2. Three-step question (easy) 3. Climb stairs with the lowest cost (easy) 4. Decoding method (medium) Introduction to Dynamic Programming: Dynamic programming is a method used in mathematics, management science, computer science, economics, and bioinformatics to solve complex problems by decomposing the original problem into relatively simple […]
Dynamic Programming 01: Fibonacci Sequence Model
Nth Taibonacci number (easy) Link to topic: 1137. The Nth Taibonacci number Description of topic: The Tibonacci sequence Tn is defined as follows: T0 = 0, T1 = 1, T2 = 1, and Tn under the condition of n >= 0 + 3 = Tn + + Tn + 1 + Tn + 2 Given […]
Classic question: Intensive explanation of Fibonacci sequence
Dependence The Fibonacci sequence is a relatively classic algorithm problem. Here I personally collect most of the algorithms as a collection and record my own growth. Of course, all of this is some insights gained after reading a little algorithm books. In the amazement, I gained some new perspectives to look at recursion, and strengthened […]

LLVM(1) Fibonacci instance
Fibonacci calculation is a very classic case. Let’s use the two writing methods of Fibonacci to compare the writing differences between ordinary C functions and LLVM IR. Ordinary C function writing #include <algorithm> #include <cstdlib> #include <memory> #include <string> #include <vector> #include <iostream> using namespace std; int fib(int x) {<!– –> if (x <= 2) […]
