When solving the optimization problem with constraints, the Laplace multiplier method and the kkt condition are two very important methods. For the optimization problem of equality constraints, the optimal value can be obtained using the Laplace multiplier method. If there is an inequality constraint, the kkt condition can be used to obtain the optimal value. Of course, the results obtained by these two met
The Lagrange multiplier method is often used to solve the optimization problem.To give a simple example, f (x) =x2+y2, the constraint is H (x, y) =x+y-1=0, this example is very simple, simple enough to not need to use Lagrange multiplier method to solve.Figure just to indicate, please ignore the proportion of the wrong place, the red and green lines are the contours of the target function, the Blue line is
Exploring recursive APS and CPS in c #
Accumulator passing style)
Tail recursion is optimized so that the stack does not need to save the last returned address/status value, so that the recursive function is treated as a common function call.
Recursion is actually dependent on the previous value to calculate the next value. If we can save the last value and pass it in the next call without directly referencing the value returned by the function. So th

Because my personal understanding of any framework is not in place or the framework's own limitations, you may encounter some problems in project implementation. Below I will introduce several problems in the development process of DWZ. This article also makes sense if it helps you.1. tree menu display problems
The built-in tree control of DWZ is good for menu display, but it is too limited to display t

Network environment:1. The core switch is the Huawei brand, on this basis, and made a second core. Both the Cisco AC2504 and Poe switches are connected on the secondary core, under the Poe switch, connected to the original VLAN 40 on the Cisco AP1401,AC, and the newly created vlan42.WORKAROUND: 1. First look at the configuration on the AC, after viewing no errors, but on the AC ping VLAN 42 network management, how also ping does not pass, and Ping VLAN 40 network management, is also not through,

1. Background
One day, when I was writing code, I accidentally opened the String Hashcode method. Then a general look at the implementation of Hashcode, the discovery is not very complicated. But I found a strange number from the source code, that is, the protagonist of this article 31. This number is not a constant declaration, so it is impossible to infer the use of this number literally. Then with doubt and cur
The Lagrange multiplier method (Lagrange Multiplier) and Kkt (Karush-kuhn-tucker) conditions are important methods for solving constrained optimization problems, using Lagrange multiplier method when there are equality constraints, and using KKT conditions when there are unequal constraints. The premise is: only when the objective function is a convex function, t
