pipe
某石油公司计划建造一条由东向西的主输油管道。该管道要穿过一个有n 口油井的油田。从每口油井都要有一条输油管道沿最短路经(或南或北)与主管道相连。如果给定n 口油井的位置,即它们的x 坐标(东西向)和y 坐标(南北向),应如何确定主管道的最优位置, 即使各油井到主管道之间的输油管道长度总和最小的位置?证明可在线性时间内确定主管道的最优位置。(An oil company plans to construct a east to west from the main pipeline. The pipeline to pass through an oil field n wells. Wells from each must have a pipeline along the shortest path (or South or North) connected with the competent Road. If given the location of oil wells in n, that is, their x coordinates (east-west) and y coordinates (north-south), should be how to determine the optimal position in charge of Road, even if the wells to the pipeline in charge of Road between the sum of the smallest length location? proved to be linear time to determine the optimal position in charge of Road.)

fminsearchbnd
Fminsearch不承认的约束限制。
不过简单的转换方法存在
转换成一个绑定的约束问题
无约束问题。
Fminsearchbnd用于酷似fminsearch,
除了边界应用到变量。
应用于国内的界限,利用
改造中的变量。 (二次型
单式,双罪恶界(十)。)
具有包容性的不平等的界限,它承认
边界值本身,但不准
在所有函数之外的范围评估。
请注意,fminsearchbnd允许用户准确地固定在某个给定值通过设置一个变量的确切范围相同的值。
(Fminsearch does not admit bound constraints.
However simple transformation methods exist to
convert a bound constrained problem into an
unconstrained problem.
Fminsearchbnd is used exactly like fminsearch,
except that bounds are applied to the variables.
The bounds are applied internally, using a
transformation of the variables. (Quadratic for
single bounds, sin(x) for dual bounds.)
The bounds are inclusive inequalities, which admit
the boundary values themselves, but will not permit
ANY function evaluations outside the bounds.
Note that fminsearchbnd allows the user to exactly fix a variable at some given value, by setting both bounds to the exact same value.
