Query: The worst book ever

I bought this book because it has source code for simulated annealing, genetic algorithms, tabu search and neural networks.I have used the three first source code and ... they are so buggy.They're wrote in C but doesn't compile due to evident syntax errors (so evident, are they here so as to made these source code unusable ?).The content of the book is not equilibrate (some metaheuristics aren't discussed thoroughly).If the authors use there source code, I think evereything presented in this book is completely false.Don't buy it, there are some better books to buy.
