- 1 Intro
- 2 Cutting Planes Measures Length Length of a proof: # of lines (steps) Can always do length O(2 ) Sometimes need length exp(n.)
- 3 Weights in Cutting Planes Weight 2 enough, but length might blow-up.
- 4 Large Weights are Needed in Cutting Planes Space Length of a proof: # of lines (steps) Space of a proof: # of lines in memory Weight of a proof: largest weight
- 5 Cutting Planes to Communication Evaluate LTF with distributed variables.
- 6 Lifting with Simple Gadgets Want fog hard for deterministic communication. ► Probleme usual gadgets too strong. Also hard for randomized / GT oracle.
- 7 More Applications: Circuits Circuits vs Formulas Monotone circuit: 0/1 values on wires; AND, OR gates. Monotone formula: tree-like monotone circuit. Theorem exp((n/polylogre)) separation between mono…
