Transcribed Image Text:After a few computer science courses, students may start to
get the feeling that programs can always be written to
solve any computational problem. Writing the program may
be hard work. For example, it may involve learning a
difficult technique. And many hours of debugging. But
with enough time and effort, the program can be written.
So it may come as a surprise that this is not the case:
there are computational problems for which no program
exists. And these are not ill-defined problems (Can a
computer fall in love?) or uninteresting toy problems.
These are precisely defined problems with important
practical applications.
