/** 题目:Solve Equation 链接:http://acm.hnust.edu.cn/JudgeOnline/problem.php?id=1643 //最终来源neu oj 2014新生选拔赛题 题意:给定两个数的和以及他们的最小公倍数,求这两个数. 思路: x+y=A lcm(x,y)=B => x*y/gcd(x,y)=B 要把这两个公式联立,那么必须消掉gcd: 设:d = gcd(x,y), x = kx*d, y = ky*d; kx与ky互质: x+y=A => d(…

背景 由项目中需要根据一些已有数据学习出一个y=ax+b的一元二项式,给定了x,y的一些样本数据,通过梯度下降或最小二乘法做多项式拟合得到a.b,解决该问题时,首先想到的是通过spark mllib去学习,可是结果并不理想:少量的文档,参数也很难调整.于是转变了解决问题的方式:采用了最小二乘法做多项式拟合. 最小二乘法多项式拟合描述下: (以下参考:https://blog.csdn.net/funnyrand/article/details/46742561) 假设给定的数据点和其对应的函数值…

关节空间 VS 操作空间 关节空间与操作空间轨迹规划流程图如下(上标$i$和$f$分别代表起始位置initial和目标位置final): 在关节空间内进行轨迹规划有如下优点: 在线运算量更小,即无需进行机器人的逆解或正解解算 不受机器人奇异构型影响 可以根据机器人或驱动器手册直接确定最大速度或力矩 其缺点是对应操作空间的轨迹无法预测,增加了机械臂与环境碰撞的可能.例如,考虑下面的二连杆机构,关节运动的限制为:$0^{\circ} \le \theta_1 \le 180^{\circ}$,$0^…
