change chunk selection strategy to meet Peerstreamer one
change to peerstreamer type of peer/chunk selection
Add per-edge-events feature to SSSim.
This feature make the simulator acts on per-edge basis rather than on per-node basis.It only works with the event-driven mode.
Add gurobi version for the WuLi optimization algorithm algorithm
After installing the gurobi library in the system, the file "gurobi.sh" should be modified accordingly and sourced before compilation.http://www.gurobi.com/
Fix bug on Wu-Li algorithm, source output capacity
fix bug on source output capacity. In SSSim source always outputs one chunk per chunktime
Fix neighbourhood limit bug in Wu-Li optimization
refactor Makefile due to a compilation error with lpsolve library
fix bug on the node output limit
Refactor with bug fix on A_ij
Refactor inner representation of ajacency matrices
The matrix element A_ij indicates the edge from node j to node i
refactor Wu-Li implementation taking into account the peculiar implementation of transition matrix in SSSim
The element A_ij indicates the edge from node j to node i
Merge Wu-Li algorithm integration feature
add Wu and Li optimization algorithm.
The functionality is activated by loading a graph file with the option ",wuli"
Add per-link events feature
add per-link events.
Add a new flag (-E) to turn on the per-link event. This implies the event-driven mode (-e).Each peer i sends an offer to its neighbor j every offer_interval times probability of j seconds, deterministically.
add .test and .edges to gitignore
add optimization module derived from the paper "Optimal Rate Allocation in Overlay Content Distribution" - actual (centralized) algorithm- lpsolve optimization library as a submodule- test case (really minimal due to the difficulty to solve the optimization problem by hand)
add helper functions to the matrix modules- create a zero matrix- dump a matrix into a .edge file
fix usage print alignment
add auto-convergence feature; simulation stops after delay convergence is reached, a chunk analysis window size can be specified
merge the delay_log feature, solve conflicts
