You could take the "it's pointless if <golflang> does it better" viewpoint even further, though, and just never bother golfing anything because <golflang> already exists and will win every time over <mylang> in a no-hold-barred cage match.
The judge-each-language-separate thing is the right way of going about it.
The IUPAC International Chemical Identifier (InChI /ˈɪntʃiː/ IN-chee or /ˈɪŋkiː/ ING-kee) is a textual identifier for chemical substances, designed to provide a standard and human-readable way to encode molecular information and to facilitate the search for such information in databases and on the web. Initially developed by IUPAC and NIST during 2000–2005, the format and algorithms are non-proprietary. The continuing development of the standard has been supported since 2010 by the not-for-profit InChI Trust, of which IUPAC is a member. The current version is 1.04 and was released in September...
The simplified molecular-input line-entry system (SMILES) is a specification in form of a line notation for describing the structure of chemical molecules using short ASCII strings. SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the molecules.
The original SMILES specification was initiated by the author David Weininger at the USEPA Mid-Continent Ecology Division Laboratory in Duluth in the 1980s. Acknowledged for their parts in the early development were "Gilman Veith and Rose Russo (USEPA) and Albert Leo...
@algorithmshark Ideally, it shouldn't be a problem, because yes, winning overall isn't the point. There are many people who view that differently though, and it does spoil the fun for them (which, you could say, is "their fault", but I'm sure the OP would still like their submissions if they'd otherwise write them)
Find the Molecule
Finding a molecule from a formula is like completing a jigsaw puzzle without the picture: it takes a long time for a human to do it but a computer can do it quicker.
What you have to do is, given a chemical formula, output the molecular structure ...
