Global variables
GeoLatency : (Dictionary) Latency based on geographical locations
Forbid constraint: (Dictionary) Each task in the list in the values is forbiden to be mapped on the respective host key
Restrict constraint: (Dictionary) Each task in the keys is required to be mapped on the respective host in the values
Distribute constraint: (List of tuples) The tasks in each tuple pair should be mapped in different hosts
Enc_connections: (List of tuples) The tasks in each tuple pair should be mapped in hosts connected securely
Redundancy_New: (List) the applications required to be created
Latency: (Dictionary) The pairs of tasks in the lists in the values should be mapped in hosts having latency less or equal to the respective latency values in the keys.
HostsLatency: (Dictionary) The pairs of hosts in the lists in the values are connected with a latency equal to the respective keys
Mappings: (Dictionary) the keys are the hosts and the lists in the values are the tasks mapped on the respective host
