counting similiarities between strelka2.0 and fruit2.1
Posted: Fri Aug 22, 2008 5:01 am
Based on the following thread I would like to count identical stuff
in a way that it is easy to find the identities
http://www.talkchess.com/forum/viewtopi ... 95&start=0
comparison
1)Fruit :protocol.cpp lines 493-507 and Strelka parsc.c lines 628-637
9 identical or equivalent lines
2)Fruit Posix.cpp lines 39-108
Strelka parse.c lines 77-100
19 identical or equivalent parts
Total number of similiarities so far 28 when I am not sure if it is fair to count all of them as similiarities because I also have the function input_available() that is written different but I also have for example
if (stdin->_cnt > 0) return 1;
Note that I did not copy input_available() from fruit because movei's code was written before fruit but people clearly helped me with the code of input_available() and unlike some genius people who claim that they did not start from code of other people I have no chance to write input_available() from scratch without code of other people.
I hope somebody can continue the analysis.
