Dear friends,
I met an issue similar as the one Robert asked before. I tried to install/build ceres-sovler on OX El Capitan(10.11.6). It seemed that neither `brew install homebrew/science/ceres-solver` nor `brew tap homebrew/science` work for me.
$ brew install homebrew/science/ceres-solver
Updating Homebrew...
Error: No available formula with the name "homebrew/science/ceres-solver"

Error: No previously deleted formula found.

Error: No similarly named formulae found.

Error: No formulae found in taps.
$ brew tap homebrew/science
$ brew install ceres-solver
Error: No available formula with the name "ceres-solver"
==> Searching for a previously deleted formula...
Error: No previously deleted formula found.
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
Error: No formulae found in taps.
Actually I got the following information when I executed `$ brew tap homebrew/science`
Updating Homebrew...

Tapped 669 formulae (705 files, 2.0MB)
And I did see the file ceres-solver.rb in the directory '/usr/local/Library/Taps/homebrew/homebrew-science' thus I cannot understand the reason why brew complained no such a formula.
Many Thanks for any help,
