示例1: step
# 需要導入模塊: import Vector [as 別名]
# 或者: from Vector import cost [as 別名]
def step(p1,p2):#radius=1
X1 = Vector(p1,p2)
for t in frange(0, pi*2, pi/4):
X = Vector(p1 + (cos(t)), p2 + (sin(t)))
if X.cost() < X1.cost():
X1.equals(X)
return X1示例2: runRandomSearch
# 需要導入模塊: import Vector [as 別名]
# 或者: from Vector import cost [as 別名]
def runRandomSearch():
startTime = clock()
vector = Vector(random()*DOMAIN_LIMIT,random()*DOMAIN_LIMIT)
minc= vector.cost()
while(clock() - startTime < MAX_RUN_TIME):
global PROBE_COUNT1

vector = Vector(random()*DOMAIN_LIMIT,random()*DOMAIN_LIMIT)
if(vector.cost() < minc):

print('2. Random Probing used', PROBE_COUNT1, 'probes.')
print('Vector =', vector, 'Cost =', round(minc,5))
print('---Search time =', round(clock() - startTime, 2), 'seconds\n')示例3: nextTriangle
# 需要導入模塊: import Vector [as 別名]
# 或者: from Vector import cost [as 別名]
def nextTriangle(A,B,C):
[B,C,A] = Vector.sort([A,B,C])
