Linear Programming Definition:
To satisfy the optimal goal of constraint, the goal is the linear function of the variable, and the constraint is the equal or unequal expression of the variable.
Simplex algorithm
1 Relaxation variables are non-negative variables that convert inequalities to equalityFor example, to turn F (xi) >0 into xj= F (xi), then XJ is the relaxation variable

JQuery's animate does not support the backgroundPosition solution on Firefox. jqueryanimate
JQuery's animate is a very useful stuff, but some animation effects are not well supported. For example, Firefox, an artifact like backgroundPosition, cannot be used, so I wrote it myself.

the concept of two or more variables in this solution. If we want to think of F as two variables, such as p and q functions, we can simply write
(FP) q
(This is the result of function FP acting on Q ). Consider the three variable functions.
(FP) q) R,
And so on.
Let's introduceAbstraction. For this reason, we use the Greek letter Lambda (lambda), which is followed by a letter that represents a qu function. For example, when talking about X, we regard it as a "dummy variable ". Any variable X in

In general, the method to implement the positioning animation of the background image is very simple and compatible with various iyjt:1$ (Elem). animate ({backgroundPositionX: '-39px', backgroundPositionY: '-39px'}, 500 );However, Firefox does not support this method. After searching by Google for half a day, I finally found a solution, that is, the $. fx. step Method of jQuery extension:

Generally, it is easy to implement a Background Image Positioning animation. It is compatible with various iyjt: 1 $ (elem ). animate ({backgroundPositionX: amp; #39;-39px amp; #39;, backgroundPositionY: amp; #39;-39px amp; #39 ;}, 500); but Firefox does not support this method ..

The property value is usually a number or it can be a hide,show,toggle keyword
A property value can also be an array form, the first array element is the final state of the property, and the second array element is the easing function
You cannot use Margin-left in this form, but you need to use hump form MarginLeft
You can use EM and%, or you can use += or -= let elements do relative motion.
If duration=0, then complete the animation directly

The eight Queens problem is a typical case of backtracking algorithms, in backtracking, often blindly searching, consuming too much search time. In this experiment, using heuristic search, the search is not either a branch, but the selection of the best branch down search. By defining the state space, operation rules, and search strategy, we can get a solution of the original problem clearly and quickly.The eight Queens question is a chess-based question: how can you place eight queens on an 8x8
simplex (see chapter II for the content) can be expressed as:
It is visible that the mixed policy set x corresponds to the convex set (simplex) 1-1 that is generated by the pure policy set S (mathematically isomorphic), therefore, the mixed policy set X "can be considered" as the convex set (simplex) extended by the pure policy set S, and set S is the pole subs
