Revit learning path 01_Revit basics, revit path 01_revitPreface:
This category records the path to Revit learning. Beginners will inevitably have a blind eye. You are welcome to join us!Revit Introduction
Revit is a modeling software built for Building Information Modeling (BIM. With the rise of the concept of BIM in China, major design institutes have increased their demand for Revit modeling, and the seco
= ' Hello ';
Console.log (foo);
};
SayHello (); Logs ' Hello '
console.log (foo);//Logs ' world '
After the function is set, you can see the change in the value of the variable in the function:
var myfunction = function () {
var foo = ' Hello ';
var myfn = function () {
console.log (foo);
};
foo = ' World ';
return myfn;
};
var f = myfunction ();
f (); Logs ' world '--haha

? Assume that the run time of ramdom (0, 1) is a constant.
Solution 1:
Analysis: Assume K = B-A + 1. Then, the essence of random (A, B) is to select a random probability from K numbers, which may be represented by random (k. Assume that a round of operations is performed in this way. Using Random () to generate K series S = (R1, R2,..., rk ). If R1 = R2 =... = rk, this round of operation will be voided and re-executed; otherwise, if rI = 0, the number of I will be eliminated, and the problem wi

The optimization of vertical search results includes the control of search results and the optimization of sorting, among which the ranking is the most serious. In this paper, we will thoroughly explore the evolutionary process of the vertical search ranking model, and finally deduce the ordering of the BM25 model. Then we'll show you how to modify Lucene's sort source code, and the next one will delve into the current hot machine learning sort in vertical search. The structure of the article is
