the answer is that we have to pass all  of the data into transition function except for the previous state.…

n most situations, a single cost function will not be sufficient to produce complex vehicle behavior. In this quiz, we'd like you to implement one more cost function in C++. We will use these two C++ cost functions later in the lesson. The goal with…

In the previous quizzes, you designed a cost function to choose a lane when trying to reach a goal in highway driving: cost=1−e​−​​∣Δd∣​​​​/​Δs Here, Δ was the lateral distance between the goal lane and the final chosen lane, and Δ was the longitudin…

Designing cost functions is difficult and getting them all to cooperate to produce reasionable vehicle behavior is hard. some of the difficulties associated with cost function design include solving new problems without unsolving old ones. when you a…

A  key part of getting transitions to happen when we want  them to is the design of reasonable cost functions. we want to penalize and reward the right things. I am going to work through an example of  one way you  might think about designing  a cost…

One way to implement a transition function is by generating rough trajectories for each accessible "next state" and then finding the best. To "find the best" we generally use cost functions. We can then figure out how costly each rough…

  In the image above, the blue self driving car (bottom left) is trying to get to the goal (gold star). It's currently in the correct lane but the green car is going very slowly, so it considers whether it should perform a lane change (LC) or just ke…

关于transition的几个基本点: 1. transition()是针对与每个DOM element的,每个DOM element的transition并不会影响其他DOM element的transition操作: 2. 对于每一个DOM element的transition每次只能执行一个,如果在一个DOM element上添加了许多transition操作,只有最后一个会起作用,前面的都会被覆盖掉.但是例外是,当这些transition是chaining的形式连接的时候,这些trans…

刷题备忘录,for bug-free leetcode 396. Rotate Function 题意: Given an array of integers A and let n to be its length. Assume Bk to be an array obtained by rotating the array A k positions clock-wise, we define a "rotation function" F on A as follow: F(k…

刷题备忘录,for bug-free 招行面试题--求无序数组最长连续序列的长度,这里连续指的是值连续--间隔为1,并不是数值的位置连续 问题: 给出一个未排序的整数数组,找出最长的连续元素序列的长度. 如: 给出[100, 4, 200, 1, 3, 2], 最长的连续元素序列是[1, 2, 3, 4].返回它的长度:4. 你的算法必须有O(n)的时间复杂度 . 解法: 初始思路 要找连续的元素,第一反应一般是先把数组排序.但悲剧的是题目中明确要求了O(n)的时间复杂度,要做一次排序,是不能达…
