terminate called after throwing an instance of 'std::logic_error'

[AlexisPister]

Hello,

I get the following error when I try to execute the main file.
"terminate called after throwing an instance of 'std::logic_error'
what(): basic_string::_M_construct null not valid
Aborted"

Here is the command I execute : "./main 50 2 0.1 20 2 2 2 0.2 0.2"
