Mathematical functions simplify programming for mathematical and geometric processes. When you use these functions, remember that some functions can be obtained from other functions. radians = degrees * pi/180 degrees = radians * 180/PI PI = 3.1415926535897932 Natural logarithm: E = 2.718322 Sin (a) = A/C Cos (a) = b/c Tan (a) = A/b Sec (a) = 1/cos (a) Cosec (a) = 1/sin (a) Cotan (a) = 1/tan (a) Arcsin (x) = Atn (X/sqr (-x*x+1)) Arccos (x) = Atn (-x/s

. The ratio is the angle of the side length divided by the angle of the adjacent side length of the quotient. To convert the angle to radians, multiply the angle by pi/180/180. To convert radians to angles, multiply radians by 180/pi. Example This example uses the TAN function to find the tangent of a corner (tan ()). Dim MyAngle, MyCotangent MyAngle = 1.3 ' defines the angle (in radians). MyCotangent = 1/tan (myangle) ' uses tangent to compute cotangent (cot ()). Notes The following is a list o

the sequential search algorithm is easy to get into local optimal value, but if the region of the optimal solution is too small (such as the so-called "golf Hole" terrain), simulated annealing is difficult to solve.(3) Genetic algorithm (GA, genetic algorithms)Genetic algorithms can be used to refer to genetic algorithms for introduction.The algorithm description: First randomly produces a batch of feature subsets, and evaluates these feature subsets

mining with the higher cost algorithm in the reduced data set. Because of its very high cost, the spatial correlation method needs further optimization. For spatial data, the relevance of geographical location can be found by analyzing the association rules. For example, 85% of the large towns near the highway are adjacent to water, or the parking lot is found to be adjacent to the golf course. The research direction of 3 spatial data mining techno
