) Analysis: First we need to know what is fixed noiseFixed noise is caused by the fact that the target function f itself is too large for QF. If the QF of F itself is too large, then it is not easy to use H to fit this higher objective function, so the fixed noise is large. When we use the smaller h ' instead of H to fit F, because H ' is smaller, the fitting degree of f is even worse, so the deterministic noise will increase!(3) Answer: Increasing second item2. The second question(1) Test instr

There are a lot of articles on the deadlock of universal joints, but the writing is more cumbersome, this problem only need to know a concept.In robotics This problem is generally referred to as the Kinetic singularity (Kinematic singularity). 1, you can see the connection axis has three rotating joints, rotating Joint 1 is around the X6 axis rotation, rotating Joint 2 is around the Y6 axis rotation, rotating Joint 3 is around Z6 axis of rotation.

Bourne shell does not support arithmetic. But in bash and Korn shell, it is generally not used. When using expr, the variable is still processed as a string, and it is not flexible enough to process spaces. It is required to use spaces to separate variables in the expression. $ z=5$ z=`expr $z+1` ---- Need spaces around + sign.$ echo $z5+1$ z=`expr $z + 1`$ echo $z6 Let The built-in bash and Korn shell commands for processing arithmetic operations
