The free version of Modelsim is a 32-bit binary and therefore requires certain 32-bit libraries in order to work correctly. For Ubunutu, install the following packages
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32ncurses6 libxft2 libxft2:i386 libxext6 libxext6:i386 
Ignore this if you have not encountered any issue with the installation and running of ModelSim and Quartus on your system. You are very lucky. (Just Kidding! You have surely had this issue, only sorted.)
Hence assuming you have been following the procedure given in this guide. Most certainly, Quartus will install jsut fine, and so will ModelSim. The issue is in launching due to inappropriate linking etc.
This is the simplest error you would encounter. Navigate to the modelsim_ase folder and run:
The Y Combinator is a classic lambda calculus construct that many people find baffling. Here's my attempt to explain it as clearly as possible (no promises!). Familiarity with Haskell syntax is assumed.
The problem we're trying to solve is how to write an anonymous function (a "lambda") that is recursive. Normally, if you want to write a recursive function, it looks like this:
fac n = if n == 0 then 1
else n * fac (n-1)
