Keep in mind that you still would be allowing for non-existent dates such as February 31 or November 31.
Based on the fact that was stated that the format of the files is:
filename<date>.dat
the regular expression would be strict enough, since it's fair to assume that whatever program produces these output files produces them with a valid date in the file name.

If other files are around with a similar format, your regular expression, even though it's more strict, would be as useless as mine. Unless ofcourse you promote the filosophy that a statement is better if it has a smaller chance on producing errors.

The only valid option, if files with similar patterns are around, is to isolate the date part from the filename and use e.g. a date conversion command/tool on that pattern and test for the return code.

SDPA(1) 						      General Commands Manual							   SDPA(1)

NAME

       SDPA - High-performance software package for SemiDefinite Programs

SYNOPSIS

       sdpa DataFile OutputFile [InitialPtFile] [-pt parameters] [-dimacs] [-numThreads  numThreads]
       sdpa [options] files...
       sdpa --version

DESCRIPTION

       sdpa  - "SDPA (SemiDefinite Programming Algorithm)" is one of the most efficient and stable software packages for solving SDPs based on the
       primal-dual interior-point method.

       SDP (SemiDefinite Program) is used for financial engineering, machine learning, control theory, sensor network problem, quantum	chemistry,
       quantum information, combinatorial optimizaiton, polynomial optimization, and so on.

       Futher information on SDP and SDPA can be found at
       http://sdpa.sourceforge.net/
