But there are still a large number of situations which are yet to be modelled The
reason behind this is that either the situation are found to be very complex or the
mathematical models formed are mathematically intractable Rationalised 2023-24
MATHEMATICAL MODELLING        207
The development of  the powerful computers and super computers has enabled us
to mathematically model a large number of situations (even complex situations) Due
to these fast and advanced computers, it has been possible to prepare more realistic
models which can obtain better agreements with observations
