Dimitri P. Bertsekas
1 Does NOT deserver its reputation
I don't know why this book has so much popularity so far. It is
NOT conscise, it is NOT well typesetted and the overall style is very confusing! I would recommend another book Convex Optimization by Boyd
2 A great book on Nonlinear Programming.
Bertsekas has always been one of my favorite authors. Nonlinear Programming is yet another of his masterpieces. An extremely well written book. Strongly Recommended.
3 Must-buy book
If you are an operations researcher or someone interested in the NLP topic this is a must-buy book. Rigorous, extremely coherent and well written.
