For this reason, conventional methods have certain drawbacks: weakness to noise, generating redundant nodes, requiring a great deal of input data, and so on.
Recent developments have focused on grid-based mapping methods which suffer from the drawback of their size, requiring a great deal of memory and prohibiting the use of many path-planning algorithms.
Embankment dams are often preferred to control rivers and streams passing through broad, wide valleys where only a very long barrier, requiring a great volume of material, will suffice.
The methodology employed has relatively low sample throughput and is labor-intensive, requiring a great deal of manual processing of samples in a format that is not amenable to automation.
The punched cards were entered into the mainframe computer and operated on to produce various reports (including specifications), requiring a great deal of tolerance on the part of the reader to glean information from them.
It has been a long and complex journey, at times requiring a great deal of patience and resilience from all involved, but humour has helped us to get through everything.
