The first is a method related to network design, which models the design problem as a variation of a connected dominating set problem.

It’s either a design problem or a construction problem.

For each design problem solved by a design pattern, the "canonical solution" is an adaptation of a design pattern to the context of the problem.

I think this is an implementation issue, rather than a design one.

You don’t have a training problem, you have a design problem.

This approach to design is not common in the automotive industry.

Finally, another design issue that should be corrected.

A given design problem has no single right answer.

That indicates that this is a design and/or manufacturing defect.

The job problem we have highlights the existing design and ideological problem:

The biggest problem with most comparison tables isn’t a design problem, it’s a content problem.

It might be a design problem, and if so, it is a serious one.

It’s obvious that there’s a design problem here, isn’t it?

It could be a design problem which definitely needs to be addressed.

He would therefore have no problem in recognizing a design.
