Sunderland's next match comes against Crystal Palace on Monday evening.
Allardyce has changed both personnel and formations during his brief time at Sunderland so far, but his alterations have had little impact.
However, the 60-year-old manager is not keen to give his players a run of games – as he feels it is important to work out the quality of every member of his squad.
"I am still experimenting because I need to find the system which suits the players to get results, and we are not getting those results," Allardyce said.
"I don't like to keep changing personnel or systems, but on the basis of not knowing my players that well at the moment and having two international windows since taking over when you lose the players to international duty means you get to know them even less.
"But trying to find the right system for a particular game and opposition is very important in trying to evolve the players and if we can find the system which gets us a result on a regular basis, then we won't have to change it as much.
"But until then I am still looking and hoping we can achieve the system to help us produce more victories.'
Sunderland have won just one of their four matches under Allardyce’s stewardship so far.
Although their performances have improved slightly, they have still struggled to pick up the points necessary for them to start climbing up the table.
Sunderland are currently four points away from safety, and Allardyce will be eager to find the winning formula sooner rather than later.
