Why are Suriname, Belize, and Guinea-Bissau classified as "Small Island Developing States"? // This contains the contract-level outputs. If you are using solc / Solidity (command line interface) you can use the command web3.eth.compile which will then spit out something like: This will compile your code and give you information like compiler version, etc. I think Mist is optimizing based on the fact that I had a 73% similarity when I chose "not optimized" on EtherScan and a 93% similarity when I chose optimized.
